I disagree with you. You seem keen to insult people who might hold an alternative opinion, so no doubt you’ll attack me as well.
Redhat did far more than just stymie Oracle. That you’re saying that suggests you’re either deliberately ignoring the facts (Ending CentOS 8 7 years early with no prior announcement, being massively disrespectful to the volunteer CentOS maintainers and support staff), deliberately paywalling source deliberately to target all rebuilders, not just Oracle, generally being amateurish and entitled dicks to the community through their official communications and so on) - or you simply don’t know.
About the only thing you say that is correct, is that Redhat do contribute a lot to FOSS, even now. That deserves respect, but it gets harder to do that at a personal level each time they do something simultaneously dumb and selfishly corporate. A lot of people have given Redhat a lot of space and stayed quiet out of respect of their history. Maybe they are right to, but the direction they’re heading doesn’t look healthy to me.
