It's not so much that I don't like Gmail, but I don't like Google in general. All other reasons aside, it's not a very good idea to ever put trust in an ad agency. I'd much rather support smaller companies that make money off their service or product, as opposed to Google which tries to compete in a lot of spaces in order to suck people in to its ecosystem.

Over time, I've been replacing various Google services with smaller alternatives. At this point, it's down to Youtube, which is pretty hard to beat. But it feels a lot better to provide usership to smaller businesses that could use it more.
