What Happened to Linkin Park?

I was just listening to some Reanimation and Hybrid Theory. Those are REALLY really good albums. So was Meteora, but I can't find it. Ever since the J-Z load of crap it's been downhill. Minutes to Midnight is an embarresment to old school LP fans like me. Where did all the politicality come from? Since when do they curse? I thought it was nice that they could sound good and be one of few bands that don't curse...not so much anymore. "Bleed it Out" is ok, but just for the first 30 seconds. "What I've Done" is also ok, but could they please knock it off with the tree-hugging meat-is-murder bullcrap? What happened?
