Well, Zynga and co. did this to themselves. They spammed the walls to no end, so Facebook just had to axe them. If they didn't overabuse the game posts so much, people wouldn't be so pissed and they wouldn't shut the channell down completely. More "philosophically" speaking - I am just thinking if this is not a case of preffering short term profits - "Send as much spam as possible!" - which, however, hurts in the long term (now the game posts are essentially useless).
