This sounds like FUD, do you have any references? Genuinely asking. I follow LWN reporting religiously, which in turn follows Fedora development (and associated drama) closely, and haven't seen anything said in this direction. Just had a quick look on LWN and Fedora development resources, and nothing came up.
This is what I read here and elsewhere bunch of times, which is why I said "supposedly". A quick search did not reveal any meaningful proof, though. I'll ask next time I hear someone say this.
unlikely. reference please. btrfs was the default filesystem on fedora installs last time i checked. to remove it they would have to first change that, then give it a few years before even considering removing it from the kernel. redhat could remove it because it was never default and never recommended.
