I've been using i3 up until recently. I'm trying out Gnome because it works out-of-the-box and e.g. Sway does not. Yes the software churn is rather worrying. I hope they learn from the mistakes.
Just so people are aware, I understand that things could have changed in the last 9 years. However, those kind of user experiences can permanently ruin the reputation of OSS projects.
RedHat is not a volunteer project and it ate half of Linux. Volunteer projects in fact tend to be the more stable and polished parts of it.
These complaints about Red Hat are what make no sense to me, if you believe they are "eating Linux" for the worse then I would advise you to produce a version of Linux with all of the Red Hat commits removed, and see for yourself if it's more stable and polished. It may not be, because you would likely also be removing a lot of the bug fixes they upstream.
