So far I've managed to remember this threat to my computer, but it should be opt-in, not opt-out.
I once tried Chrome - in a 'moment of madness'. It was not to my liking at all (being very restrained here - I could be rude about it!). Then, uninstalled it and had to spend a lot of time fixing things that it had borked.
I do not, ever, want this this charming offering.
