Years ago (linux-kernel 2.6 days) I found Red Hat was somewhat at odds with FSF values.

Red Hat does abide by the letter by the GPL by releasing source as legally required, but in a form that's inconvenient to work with: https://lwn.net/Articles/430098/

Apparently you could access the individual patches through your Red Hat subscription, but the conditions of the subscription prohibited you from sharing them. https://lwn.net/Articles/430132/ (see pzb's comment).

Red Hat/IBM is (presumably) doing what they believe will lead to continued commercial success in our current environment, I'm OK with that. But I don't really consider their condemnation of the FSF as anything of note beyond the loss of a donation.
