RH basically does not care, and i don’t think this is going to be financially significant for them for quite a while (iff they can legally get away with this). the people choosing to pay $600 a year per server do not care about open source, they care that they servers are running linux and have 7 days a week 4 hour support. the people that use RHEL daily and care about open source are not decision makers, and convincing higher-ups to stop paying for RHEL, migrate the entire tech stack to something else with support and pay that is a non-starter.

In a few years, the quality of the service will probably be significantly worse, and at that point servers currently on RHEL will have to be mostly replaced. at that point only will RH see a downside to doing this, and by that time the execs will have gotten their package for making Good Decisions and will have ran out of there, leaving the comunity to pick up the pieces.
