I think you're conflating different issues here. Usability, vs privacy. Chrome usability is actually better, 'not 100x worse'. I've stopped using Chrome because of the privacy issues, but let's be accurate about the issues so we build better community understanding and possibly solution.

e.g. By realising that Mozilla has better (than Chrome, but still flawed) privacy, but also issues with usability, a nice solution suggests itself: another user-focussed organisation could maintain patches to Firefox to produce a better browser fixing the regular anti-user things Moz does.
