I don't think "freedom of expression" is ever absolute, anywhere, nor do I think Theymos thinks it should be on bitcointalk (as evidenced by some of the rules, the presence of moderators, and even his banning of the last Yobit campaign).  If there was absolute freedom, then spamming would be allowed--and it's not, and I think common sense would dictate that there are limits to how shitty posts/threads can be before they get deleted.  Otherwise it's just a set up for the implosion of this forum, a scenario where there's nothing but AI-written crap and sig shitposters driving away all of the good members.

And I wonder why a lot of those good members of old did go away.  Some of them we know the reasons for, but I have a feeling some left because the level of discussion quality here has deteriorated and it's become tedious to see the same thread topics come up over and over again.  I'd really, really like to know Theymos's thoughts on this, but I don't suspect he'll give his opinion anytime soon.
