I may be missing or be incorrect on some aspects, but afaik, here’s the situation.
Red Hat has an enterprise Linux (RHEL), which costs money to use. However, they also had centos, which is exactly the same as rhel, but doesn’t include any support. Since it is exactly the same as a high quality enterprise Linux, many people running servers used it, because you know any bugs would be fixed in rhel and would come to centos as a result.
Recently, red hat decided that they don’t want to provide a 1:1 match between rhel and centos, so stopped serving centos, and created something called centos stream, which is somewhat like Opensuse tumbleweed vs leap. Many people didn’t like this, but since the source code for rhel is open source, many new Linux distributions like alma, rocky etc. popped up that basically provided a 1:1 rhel compatible distro using the rhel GitHub.
Now last week, red hat decided that they don’t want to provide free access to the rhel source code either, so alma and rocky would have to pay for access to the rhel code. The community got angry that red hat is taking Linux itself (which is open source) and makes people pay for it. Red had argues that they already contribute heavily to the Linux kernel, and that it’s not sustainable for them to give a free distro of their bread and butter. Oracle, which is widely criticized by the Linux community for being a greedy company, said red hat needs to keep the rhel code open, and Opensuse has announced that they will provide a replacement for the centos distro.
Again, I have not been following this news as closely, so if I’m wrong on anything, please correct me.
Red Hats / IBM did this to themselves when they decided to kill CentOS. There are rumors that said Red Hat/ IBM was pissed that Rocky won a NASA contract, so they decided to pull the rug, stop releasing RHEL source code to non paying customers, and add clauses to their ToS to terminate contract with customers that redistribute the source code.
But you know what, if Red Hat/ IBM didn't kill CentOS, Rocky wouldn't exist. That NASA contract would've gone to Red Hat. Oracle Linux wouldn't be as popular (because people would use CentOS), and SuSE wouldn't provide free support to Rocky and Alma. Red Hat would still be the open source darling of the linux community, and IBM would still made a buttload of money.
Instead, they got greedy and think that all those CentOS downloads equals to lost RHEL sales (classic piracy equals to lost sales fallacy) and decided to kill CentOS to increase short term profits, which sprung Rocky and Alma (which truly eating their lunch because they also offer enterprise support). Red Hat didn't learn it's lesson and double down, and now have burned all of it's remaining good reputation in the open source community.
Alma and rocky were distributing pure clones, only modifying branding. It's a scammy business model, and I agree with red hat's stance, but less so their methods.
So perhaps Red Hat should not have based their software on something that allows people to do exactly that?
Or even better, they should stop picking up software from others, modifying a tiny bit, and saying that this new modification can't be shared.
This is the real scummy behavior.
Regarding their brand, deployment software, etc... Couldn't care less if they don't distribute and forbid people from sharing that's 100% their software.
