That's nice... but Redhat's entire business is also built on the open source software contributed by tens of thousands of others, much of it licensed to them under copyleft terms like the GPL. Yes, RedHat absolutely did contribute immensely to that ecosystem, but once they (or corporate-daddy IBM) decided to take a big fat stinky dump in the collective sandbox and stopped sharing their toys, the rest of us are kinda allowed to be pissed at them, no?
"We will give you the SRPM because we legally have to, but if you actually exercise any of the rights afforded to you by the GPL that software was licensed to us under we will immediately terminate you as a customer" *may* (a court will ultimately decide) fit into some legal loophole that exists in the void between contract vs. copyright law, but it certainly does violate the spirit of term#6 of the GPL, i.e. "You may not impose any further restrictions on the recipients' exercise of the rights granted herein".
RedHat pulled what is commonly known as a "dick-move". Ef them and the horse they rode in on.
