One thing that I've always found interesting is that silicon valley has a common start up strategy that is basically: do well enough to get bought buy your bigger competition. Basically, be a threat so your VCs can cash in when a Google, Facebook, etc buys you.

I'm other words, Silicon Valley has a start up culture that feeds an anticompetitive/anti-trust ecosystem. No one complains because they are all making money. It's the users who slowly suffer and we end up were we are not with 5 companies running the modern web and Internet infrastructure.
