I don't know about Perl, but there was a long stretch of time where the only full-time paid developer of the CPython core team was a Red Hat employee, with all other core team members only able to contribute a few hours a week. I don't think that's the case anymore because IIRC Microsoft is now employing a few, but as far as I know Microsoft and Red Hat are the only two companies with any employees working on Python as a full-time job.

Yes

Red Hat is the primary corporate contributor to GCC, yes. I would guess it's probably also the largest contributor to glibc as well, but if not, it's definitely top 3.
You'll notice that for instance GCC is ahead of Clang on C++23 adoption, and that's largely because Red Hat is paying people to work on it, whereas Google who was a major sponsor of Clang/LLVM work has been decreasing their contributions there.
You've pretty well debunked this, but I took a stroll through the git repos; the commit logs tell the truth.
Python: the latest commit was from a Microsoft employee. Not to mention the creator of Python works for Microsoft now.
GCC: The commit log is overwhelmingly from: RedHat, Suse, Intel, Arm, Oracle (!), IBM and a few indie developers scattered about. I saw maybe one GNU person in the logs at the most.
Sounds like Free Software has gone corporate.... RMS might want to get his suit dry cleaned.

But Red Hat has also been increasing their contributions to LLVM, too, e.g. https://www.npopov.com/2022/12/20/This-year-in-LLVM-2022.htm...
