RH (ie IBM) only really makes money off of RHEL via support contracts. They noticed that a lot of ppl would use CENTOS to avoid paying for licenses, so they essentially killed it, they now notice that folks like Oracle are basically just using their source rebranded and selling support contracts that undercut them on their own software - so they are taking this action in a way to counter it.

Unfortunately, Alma and Rocky are going to get caught in the crossfire on this one, people are acting like this was some targeted thing at Alma or Rocky - honestly, they are likely barely on IBMs radar, this is aimed at Oracle.

IBM MBA says "money left on table, what can we do about that?" Someone suggests that GPL letter of the law only requires source be distributed with binaries, and so they decide to do that.
