Free speech advocacy was trendy with the left when the right held more institutional power. Now it's embraced (at least as a slogan) by the right. In much the same way I don't trust Apple to give a damn about software freedom, but they backed Webkit and clang for their own self interested reasons. I accept that being "on the side of free expression" means that I will need to shift political allegiances now and then as power consolidation shifts. Along the way the tools for enabling and preserving free speech get better and better though. Long live the anti-establishment wingnut right... until they win, then I'll be hanging with Jimmy Dore.
