> "nobody left there with enough courage to stop them"

I'd add it's also that there's nobody left to compete with them, either. They own the only desktop browser that matters, and basically the entire concept of the mobile phone itself outside the US (Android), and it seems like 50% or so of the corporate email market, 80% of the consumer email market, a high percentage of the advertising market. I don't think pre-1984 AT&T had half the dominance Google does.
