Thoughts on RHEL going closed source ? - Mander

I’m curious about what you think on how it will affect the Linux community (especially RHEL based dustros like Fedora or Rocky).

They aren't going closed source though? Just not providing source to everyone. But everyone who gets binaries from them still gets access to the source code. Unless I'm missing something?
I am worried about the impact it will have on clone distros like Alma linux.
The code can still be accessed from a free developer account, but I'm not sure about the implications it will have on the legalities and licences.
