I'm not talking about "Larry And Sergey have decreed that Evil Shall Happen!" I'm talking about broad economic incentives. Since I don't work for Google, I have to treat them as a black box; I see what goes in, I see what comes out. I know nothing of the internals, I only have one friend who actually works there. If I implied there was some kind of conspiracy, that is my fault. You're right that that would be ridiculous.

I would also criticize Google for your reasons, and they may be even more important. But this isn't a thread about those things.
