Who would possibly buy Chrome? Letting any of the large tech companies purchase it (the only possible buyers) would just give someone else monopolistic power. Chrome can’t exist as a standalone business without being even more consumer hostile.
Why not? Chrome's team isn't as prone to distracting itself as Mozilla. But there is still a lot of ancillary nonsense they get up to that wouldn't be necessary if it weren't in Google. Starting, for example, with not giving a fuck about how their product impacts ad sales.
