@sallyNULL RedHat seems to have recently decided to no longer publicly release the software, rather only convey it to customers.
That's permitted by the GPLv{2,3}, but I believe the topic being discussed is about RedHat threatening to cancel customers support contracts if they share the software (which they've been doing for years it seems).
As far as I can tell, no version of the GPL requires keeping anyone as your customer, but making people directly or implicitly agree to the further restriction of not sharing the software is a license infringement.
Unfortunately it's hard to prove such sort of infringement, as the joining terms don't specifically say that (but seem to indirectly) and RedHat can come up with many excuses as to why they denied renewing a customers support contract that's unrelated to the customer deciding to share the software.
Hey did you hear that fuss about RedHat trying to restrict source code redistribution? How's that even legally possible if plenty of the stuff they use from Fedora is GPL?
