Red Hat offers free subscriptions to developers. How doesn't it help in this case?
It expires every 12 months, and you have to take action to renew it, again with a not-very-clear path. It’s not possible to renew early (at least, I didn’t see how).
It adds extra friction: You don’t get a custom ISO or the like. Instead, you have to register your system during installation. It’s an extra step you don’t have to take.
There’s a subscriber agreement you must agree to, which not everyone wants to do.
It isn't trustworthy in the same way that the downstream rebuilds were.
