1. .Net framework is NOT bundled as notepad o minesweeper. It is
distributed separately.
2. You cannot order z/OS without VTAM and TCPIP, but this is off-topic.
BTW: You can order "enhanced security" for VTAM (Sec Lvl3), this is
optional.
3. You compare TSO to .NET, but it's bad comparison. TSO is mandatory
(you don't have to use it, but you'll get it with z/OS) part of z/OS
"bundle". You cannot order z/OS without TSO and LLA, but you can order
Windows without .NET framework and use applications written using ISV tools.
4. You can get from IBM add-ons like Ported Tools. You have to order it
explicitely, it's not "always in the bundle". However it's free of
charge. Obviously, in order to use it you have to have z/OS, computer,
server room, etc.
5. Microsoft allow you to download and use .NET as well as PowerToys,
but you have to "order" them explicitely, these are NOT part of Windows
bundle.
6. Almost every "free software" manufacturer do it for money. Sometime
it's free of charge runtime, in other case some tools making work more
convenient, etc. etc.
7. It's quite obvious that software developer buys compiler (and many
other tools) to write, and usually sell programs. So, ISV pays for the
compiler. Some compiler vendors say: "you have to pay for the compiler,
but your customer is free of charge TO US" - the customer pays only to
ISV. Some other sell compiler and runtime.

Since it's Friday and I am not doing much today, I'll jump in. When
one buys (actually licenses) a version of what is called
"MS-Windows", they get a lot of different programs all "bundled"
together. The programs which make up the .net run-time environment
are a part of this bundle. Therefore, IMO, .net run-time is an
integral part of MS-Windows and so is not "free" per se. You don't
pay for it separately, like you do for MS-Office. But you can't get
.net run-time separate from MS-Windows (well, ignoring Mono at this
point, you can't run Mono on MS-Windows). Also, you cannot legally
get and use the bundle called MS-Windows without a license. That
license may be paid for by you; or by a friend; or hidden as the
"Microsoft tax" when you purchase a PC with MS-Windows pre-installed.
.net run-time is like Internet Explorer. Both are bundled and their
use is allowed because you have a license for MS-Windows.
In opposition to this would be software such as Oracle's Java and
LibreOffice. Neither of these are distributed in the "MS-Windows
bundle". Both of these may be downloaded, installed, and used without
paying money or "other consideration". However, if you look closely
at the sites, you will see that there is a explicitly granted license
to you to allow you download, install, and use them. They are not
"public domain". Java is gratis (no cost). LibreOffice is both gratis
(no cost) and libre (you can get; modify; and redistribute).
Technically, you are not supposed to download Java, then give that
downloaded copy to another. You are only granted the right to
download Java for yourself, for use on that specific PC. Again,
unlike LibreOffice whose license allows you to redistribute it.
In the z/OS world, what exactly is z/OS? It definitely isn't free, so
what is being paid for? Is it the BCP which actually costs money; and
the rest (like TSO, LLA, VLF, DFSMSdfp, LE) are "free" just because
bundled? LE might be considered the ".net of z/OS". LE is not
cost-free! You certainly can't order z/OS without getting and using
LE. If you don't like LE as an example, what about DFSMSdfp? It is
also bundled and not part of the BCP. There is other software which
runs on z/OS which some might consider as part of z/OS. One example
is "Communications Server", aka VTAM and TCPIP. Guess what? You can
order z/OS without ordering Communications Server. It is useful?
Well, how about a batch-only image which is connected to another
system using a CTC as an NJE channel. The second image could do JES2
NJE to the batch image without the need for Communications Server.
Sounds weird to me, but what do I know of unusual requirements? There
is other software which is obviously not part of z/OS: the compilers
for example.
Anyway, the way that I think of it ".net" is not free because it's
cost is bundled into MS-Windows. Other may consider it to be "free"
because it is not separately priced. You pays your money, you takes
your choice. Either way, you pay money to MS.
