AFAIK Chromium, by default, syncs data with Google as well unless you can disable it by some custom compile flags or something. Do we seriously expect (the majority of) users to compile their own browser?

I would expect at least the major linux distros to turn said flags by default.

As I've just checked, Ubuntu doesn't. Don't know about other distros.
