While I don't think it's wise of #RedHat to try to stop 1:1 clones of #RHEL, I do think the discourse is getting much too toxic and is losing so much nuance.
Let's all remember that RedHat is not stopping with contributing patches back to upstream, nor is it stopping the huge amount of open source development they are doing (so much of your linux machines were co-designed/developed by RedHat engineers). They just don't think the RHEL clones (who are not blameless) are worth it anymore.
It seems RedHat has estimated that the "soft value" (mindshare and RHEL skilled admins) of the clones isn't worth it.
So yeah, in general, I don't think this choice is evil.
That said, I think it's a very bad move from a PR perspective, especially considering that they communicated it in the same way that every open source company communicates controversial changes.
I also think we should keep an eye on them, just in case this IS the first step in them becoming more closed.
