It would also still go in the other direction as well would it not? Meaning contributions via paid Red Hat devs would still benefit the wider Linux community, even as they close off the free forked versions.
I'm not sure exactly how much Red Hat contributes to Linux though but if I remember correctly it's quite a bit. Maybe Red Hat making more $$ = more devs. Or maybe this is just a net negative for the ecosystem code-wise (as opposed to just hurting the current users of the forked OSes) as it pushes more devs/software away from a very popular 'platform', reducing exposure, free online support on forums, testing, etc.
