Remember what I said about hearsay? Everything in Fedora is FOSS, everything in RHEL is also FOSS (because it's in CentOS Stream). All the code is released, not behind a "paywall". All that Red Hat have done is make it more difficult for companies to sell a 1:1 "bug for bug compatible" RHEL clone - those are the "free loaders" being spoken of and who they're targeting, not the Linux community, it's people like Oracle (who incidentally are also the ones fanning the flames of this drama).
I'm no fan of Canonical, but even with your description you're really sensationalising things there as well. The point is by supporting Debian you're inadvertently supporting Canonical - I don't think that's a problem myself but it seems you have double standards.
You haven't even made a case to rest.
