“I understand that Canonical has every right to make the decision about their product.”
That seems fair. There are loads of distros available so why not try something else if you don’t like Ubuntu?
Linux and other mainstream Unices such as FreeBSD or OpenBSD int al (that’s not something I ever thought I’d be able to say a few decades back) are not Windows or Apples or whatevs. You do you and not them!
If Ubuntu fails to scratch your itch then move on. Debian is the upstream for Ubuntu so you’ll probably be fine with that instead. There is loads of documentation for Debian via the wiki etc and of course most Ubuntu docs will apply as well.
