Just because there are legitimate reasons for sending all that data doesn't mean it's not also usable to track you or whatever. In fact, having all that data in the first place lowers the barrier to start using it for other things. We've seen that happen countless times. What it comes down to is that Chrome sends a whole bunch of information about me to a company who's main product is serving ads. I don't know exactly what data they send or how they use it, and that in and of itself is a major problem. In the end, sure, Firefox does the same things. But Mozilla's core business isn't selling my personal information to the highest bidder, so I trust them more than I do Google.
