I suspect most people simply don't care. I consider myself to be very hot
on personal privacy, but the news that a search engine receive my search
queries and IP address is utterly unsurprising and not anything anybody
could possibly ever do anything about.
The news that Firefox receives lots of money from Google in exchange for
simply setting one default, well, good for them! money for free software
development in exchange, not for selling their souls, but for doing
something they were *going to do anyway* and were in fact *already doing*
and *so is every other non-MS browser vendor*.
