IBM decided to only provide access to RHEL source code to those with a developer subscription, effectively putting RHEL behind a paywall and putting it behind an additional license you have to accept with your subscription. I mean, this seems to be pretty clearly against the GPL license that RHEL is not only released under but also the GPL licenses of the many components that RHEL uses. The GPL has some provision for, for example, charging money for source code distribution since that does indeed have a cost, but because they make you accept a second license with your subscription you can't just turn around and give distribute it yourself to anyone who needs it - which is what you should be able to do with any GPL software. Well, you can do it, they just reserve the right to terminate your contract if you do. So you can do it once I guess? Then afterwards you no longer have access to updates. But who's gonna make IBM answer for this? Don't think anybody really can.
