RHEL not supporting LibreOffice doesn't mean you can still install it, right? It just means RH won't offer support for it?
Also does not mean you must use Flatpak to use it, does it? Am I missing something?
If it does make sense business-wise, it's their call. I'm pretty sure they know their userbase and did the math.
I also prefer efforts put on Wayland improvements, much closer to the OS itself and relevant to several use cases.
