They weren't dying before, but they be might now.

The problem is that the value RHEL provides. For my PERSONAL projects the value is less than the cost of renewing my free license every year from them. For a company shipping a system that will in the field for a decade with minimal updates is completely that must work with minimal downtime the value they are providing is higher than what they charge.

That difference in value by users requires RedHat to balance costs the they can charge against maximizing numbers of users versus income. The catch they are running into is some people they provide little value to will just leave, but those people were providing a lot of value for customers. 100 or so ansible roles that your customers were using is suddenly no longer going to be supported, and eventually likely not to work. That is likely a net negative for value provided to customers and goes against the spirit of open source.

The people using Rocky or Alma are unlikely to see cost of RHEL being worth it. So they will go elsewhere. But having a bigger number of users running on those systems provided value and network effect for RedHat even though they are not paying. That indirect benefit is now lost.

RedHat obviously feels all of that does not provide enough value to justify the cost of possible lost sales. I think they are wrong, but maybe they are right.

Maybe they are violating the GPL which explicitly says you cannot add limitations for users sharing code. From here it sure looks questionable at best, intentionally breaking the license at worst. That will have to be left for someone else to decide.
