In my opinion these groups are just playing the game of realpolitik, taking money where it comes and making practical, calculated political moves so that they don't appear too radical for the mainstream, maybe waiting for the pendulum to swing the opposite direction. Sure they are not purists like you appear to be, and yes they are selling out. So if you don't like their tactics, try something different. Writing long exposes and character assassinations on these groups -- which probably share 90% of your opinions on actual policy but simply differ with you in method -- serves no purpose. The first thing the present administration wants to see is the factions of the left devouring each other.
