Because Paul Allen got leukemia and quit the company around 1983.
Microsoft was founded by two people: Paul Allen (the techie) and Bill Gates
(the marketer, whose father was a lawyer. Gates was a bit technical in the
8-bit days, but the last piece of code he personally wrote that shipped in a
product was the text editor for the TRS-80.)
In late '79 early '80, they heard the rumors that IBM was pondering a PC, and
Paul Allen went "any real computer will run Unix", so they got a license from
AT&T and ported the sucker, calling it "Xenix". (MS was a porting house,
they made their living porting software (mostly BASIC) from one platform to
another in those days, and porting unix was a big thing, so as the name
implies: they'd port it anywhere).
And then IBM dropped the PC's tech specs on them after they signed
non-disclosure and it said "minimum 16k of ram", and they went "okay, we need
an embedded OS". So they sent IBM to talk to Gary Kildall at Intergalactic
Digital Research (I.E. Kildall's living room) and get CP/M, but the meeting
fell through famously. But Allen knew a guy who knew a guy who had reverse
engineered CP/M from a store bought API manual as a summer project (Quick And
Dirty Operating System). They got a bank loan for $50k, bought it, and
offered it to IBM.
Remember, the original PC the floppy was optional. Dos 1.0 was only needed
if you got the optional floppy, the in-ROM basic (which was the real reason
IBM was talking to MS, the rest was just gravy) had support for the casette
tape interface built into the original PC. That was the default interface,
floppies were an expensive luxury. But microsoft had conditionally licensed
to IBM their entire rest of their software catalog (from typing tutor on up),
conditional on having a floppy drive to load them from. They went out and
got their own version of CPM so their application software deal with IBM
wouldn't fall through.
And of course IBM had two sources for everything. (As a big evil monopoly,
they understood that being on the receiving end, at the mercy of a monopoly
supplier, was a bad thing.) They even made Intel license the 8086/8088 design
to AMD so they'd have a second source. (And that's how AMD got into the
clone business.) DOS 1.0 and CP/M ran EXACTLY the same software, they were
two sources for the same thing. At first.
Paul Allen didn't give up on Unix, of course. He knew the PC memory would
grow and someday would be enough to run Unix, so in he set about making a
migration path from DOS to unix. The dos 2.0 manuals went out and said that
DOS would someday be replaced with Xenix, and in the meantime here's a lot of
unix functionality to get you used to it. He added subdirectories (using \
instead of / only because / was already the command line option indicator.
"dir /s". In 2.0 the deprecated that and changed it to "dir -s" as the
recommended method, to be unixish.) Plus device drivers, pipes and redirects
(hacked onto the CP/M base as best they could), and of course file control
blocks were replaced with file handles. The dos 2.0 manual eventual promised
they'd give DOS multiple process support (multitasking).
Dos 3.0 was mostly based on adding new hardware support, specifically hard
drives since the XT was coming out. And it's about this time (1983ish) that
Allen got sick and took a leave of absence from microsoft which he never
returned from. And Microsoft's technical side fell apart, but not until
after they shipped DOS 3.
When allen left, two things happened. 1) Gates was left with absolute power
within Microsoft and started succumbing to it. (He was always a greedy
bastard, but so are steve jobs, larry ellison, the heads of commodore and
atari, and just about everybody else in the business. Linus has his "i'm a
bastard" speech too...) 2) The technical side of Microsoft imploded (at the
mercy of marketing). Xenix was unloaded on the Santa-Cruz operation almost
immediately, and Gates allowed microsoft to be led around by the nose by IBM
for the next five years or so in place of any in-house technical agenda.
(And hence OS/2 1.0)...
Did I mention I'm writing a book on all this? (The history of linux and the
computer industry, going back to World War II...) This makes me the only
person I know who's excited about finding ~50 issues of "Compute" and
"Compute's gazette" from the mid 80's at a garage sale. An the university of
texas's library has been quite a help. So have the used book stores...
Still trying to figure out a title though. I was thinking "Penguin Uber
Alles", or maybe "The Story of Linux". Of course Richard Stallman didn't
like that title at all when I drove up to MIT to interview him. (Then again,
he tried to get me to write a different book. :)

Um, they have. Check for references to the regents of the university of
california. (Grep for it.)

Microsoft has parasitically benefited from other people's innovations from
day one. Its first product was BASIC for the Altair, based on a decade-old
(at the time) project out of Dartmouth College. DOS 1.0 they bought from the
guy who cloned it (from CP/M). Their spreadsheet was a straight clone of
Lotus 1-2-3, word was a mixed clone of wordperfect and other then-popular
word processors, they bought powerpoint, their web browser was based on code
they licensed from spyglass (violating the terms of the license, of course,
and then settling out of court for $8 million which probably came from their
donut budget...) Anybody remember the stacker lawsuit?
Name one thing Microsoft actually invented. Other than Microsoft Bob.
Open Source is just one big resource-filled wilderness to be clear-cut and
strip-mined as far as their concerned. The only problem is there's this
weird kudzu-like entity coming out of the rainforest called the GPL, that
refuses to be easily digested, and is in fact expanding back into their
territory..

I wouldn't be at all suprised if they did. It'd fit in with the history of
NT. (Version numbers really approximate, I don't have my notes with me.)
NT 1.0: the inherited OS/2 1.x code ported to 32 bit mode, sort of.
NT 2.0: 1.0 didn't work so let's try porting it to the mach microkernel.
NT 3.0: that didn't work either, so let's hire Dave Cutler (chief unix hater
at Digital research and ex-head of the VAX VMS operating system) to port VMS
on top of the steaming pile of code that is NT.
NT 3.5: punch holes in the mach microkernel to get some performance, try to
fix some of the more obvious bugs.
NT 4.0 stabilized (a bit) because dave cutler (and the team under him) was
still around. They hadn't yet again changed horses in midstream.
Eventually, with the same team working on the same code, it's bound to
stabilize a bit.) Bloated a bit as well, but that's proprietary software for
you.
And then Windows 2000 (NT 5) is proof that if you throw enough money at the
problem and put enough coats of paint over the dry rot, you can eventually
get someting with a stiff exoskeleton where the surface layers support the
wriggling mass of decay beneath the surface. It's a strange way to build an
OS, but hey, if you're willing to waste 64 megs of ram on the lower layers
you can have tons of scar tissue loaded in there you carefully try to avoid
actually using...

Somebody who works at McDonalds may actually be a master chef in their spare
time. Doesn't mean it has anything to do with their day job.

And we thank stallman. Now if the FSF would just get a marketing arm...
(It's not a bad word if it gets him to translate his "Don't call it Linux"
campaign into something that expends political capital a bit more wisely and
gets his message across clearly when he ISN'T preaching to the choir.)
