The thing about RH is that some software is only supported on it. RH is owned by IBM, and judging from comments on slashdot by one person who worked for them, RH always resented that companies would use CentOS or whatever for free. Firstly, when ScientificLinux got popular (people were mad at CentOS because the main developer had the temerity to get married overseas, and therefore, CentOS was late with a point release--IIRC, anyway--and people began turning to ScientficLinux. So, RH quickly hired Scientific's main developer. Then they took over CentOS, I think in 2014 or 15, and as a lot of people know, killed it in 2020 for CentOS stream. So, it seems they're playing a long game. They have seemed to be the Microsoft of Linuxes for a long time now. According to further comments from the one I mentioned, from someone who worked for RH for awhile, they always considered the companies that used CentOS (this was back in 2019) to be freeloaders.
Anyway, IBM has deep pockets and I don't really understand the fine details, but what they're doing is honoring the letter, if not the spirit, of the GPL so I don't think anyone is going to challenge it. Sadly, at least in the US, most sysadmin jobs that aren't Windows, are RH--or up till now at least, RH clones.
