You're incorrect. Red Hat (and SUSE)'s distributions are free-as-in-freedom software (or at the very least, the majority of the distribution is free -- the link you posted is complaining about a very small minority of the software that is part of such distributions [which is a problem but is not as big of a problem as you claim]). The fact that you won't get official updates after a trial period (or if your subscription runs out) isn't against the principles of free software. As a user, you still have the source code and have the freedom to maintain the distribution yourself (nobody does, but the freedom is still there).
