Many people have noted that in the last year or so Blizzard has been acting kinda strange. CM's have became more uptight with information, dev's seem to be slacking, and something just feels off. Well her is my theory:
Blizzard pays millions of dollars for bandwidth, servers, the upkeep and maintenance, and this is just for WoW. Now Blizzard has another very large MMO coming out in the future, Thor. I'm thinking they are trying to slowly drive WoW into the ground in order to free up servers for Thor and Diablo 3. This way blizzard has more games out for people to pay for without having to pay more for servers. Given that with the new games you would have to pay for the game + monthly fee then it would be a net profit then just your normal wow fee.
Or maybe my tinfoil hat is too tight.

Also this would explain why this recent patch went over so badly. The A team went on to D3 and Thor, while the interns / new people were stuck with wow to practice on before their new MMO's came out.
