I did try it a couple times in the past, it just never quite felt like home. I don't know why, I couldn't give you an objective reason as to why I didn't like it. I probably should give it another try soon.
Once a debian...
Also we've seen what Red Hat/IBM did with CentOS, they might pull something similar to Fedora, It's unlikely which make it very appealing for IBM
I don't think they could actually do that. They provide funding for Fedora's infra, but they don't make up the majority of contributors, and if you read through the actual governence model (note that the higher up the group, the less power it seems to have — the Fedora Council or whatever basically only exists to solve disputes that bubble up from lower, entirely community run and elected, groups), while Red Hat does have some influence/positions, they have far, far less power than the community just by numbers and also by who controls various things, and everything is also done by consensus to boot, so Red Hat couldn't just unilaterally change how Fedora works. At best they could withdraw funding (making Fedora less well-tested) and their people on the governing bodies, but it wouldn't amount to much. And Fedora is upstream from Red Hat Linux and CentOS and provides them with an utterly massive amount of labor and testing they couldn't hope to achieve on their own that they get by virtue of it being FOSS, so it would be a pure harm to them to shut Fedora down or make it closed even if they could, whereas the story is very different with CentOS and RHEL.
I've been using fedora for the last year and a half and been enjoying it much more then when I gave it a try 9 years ago.
Not only did it get much needed improvements everywhere, but software availability has improved by a lot. The official repos has more software available than it used to and flatpak helps compliment it a bunch. But what sealed the deal was using distrobox to easily create containers based on any popular distros that integrate almost seamlessly with your user/session. There are gotchas and it's not meant for more casual users, but you can have pretty much any software available from other distros to supplant missing stuff on fedora.
Also RPM Fusion helps easily skirt over any copyright restricted software. It's fairly easy to install the full set of hardware accelerated video codecs for your hardware this way.
