I don't look at much Linux stuff these days but IBM RHEL closed source is
popping up everywhere. I only looked at a couple items out of interest. How
dare you not read anything. You asked for a reference which a quick search
returned the RedHat response I provided. An arrogant response is warranted
because you didn't make a basic attempt to find something that returns so many
hits.

The article denies but does not refute. RHEL says that paywall and NDA isn't
closed source. The Linux community says open source is not restricted source.
They consider this to be closed source but it's never been tested by the courts.

By "spirit", I'm saying opinion. As we learned from SCOTUS interpretation of
the Constitution, it's open to opinion otherwise every SCOTUS decision would be
unanimous.

Customers care. For instance, large SAP customers choose DB2 on z/OS because
DB2 on other platforms is not performant nor as reliable. For these customers
to move to RHEL on z, Linux must include DB2 for z/OS without the need for z/OS.

Sysplex is both software combined with hardware constructs. Shared dasd,
coupling facilities and other hardware combined with various software
components are required for sysplex.

.
Without required structures in the coupling facility, you can't have sysplex.
You may not be aware of these structures but nonetheless they are a hardware
requirement for sysplex.

How dare I fail to read everything that you do!
If this was a Linux list perhaps your arrogant response would be warranted.

That page doesn't say what you said it says, "IBM RHEL announced it's move to
closed source (IBM RedHat Enterprise Linux)." Not only does it not say that, it
refutes it.

Yes, that is consistent with the GPL.

What does that mean? GPL has always allowed you to charge for a GPL licensed
program.
Version 3 says it this way to make it clear:
"You may charge any price or no price for each copy that you convey, and you
may offer support or warranty protection for a fee."

Of course not. Who cares? For one thing, the I/O interfaces are different. For
another, z/OS is EBCDIC and Linux is not.

Yes, I know what Sysplex is, and it is decades older than z16. Sysplex is a
software construct, not hardware, although certain hardware is required to
implement it.
>At the moment, z/OS is the OS of choice for utilizing sysplex.
No. z/OS (and MVS before it) is the operating system that implements Sysplex.
It is not something implemented in hardware that z/OS utilizes
