That's the thing -- I do feel strongly about privacy. That's why I don't see the point in switching to another US based service. Better to use a European or Asian provider or roll your own.
I just bloody switched to fastmail because I thought it was Australian - and unfortunately I really like it. Gutted to hear it's hosted in USA, kinda negates the point of my effort switching away.
But if you dont feel strongly about issues such as privacy, of course you dont see the point.
