Yeah, they're pretty decent people. I'm sure if the government went to them with a warrant or something, they'd fully comply, but they genuinely care about privacy and customers, and would be unlikely to do anything evil. They're also rich enough that I doubt they'd be forced into a sale to some crappy entity who would then abuse things, and their privacy policy is decent enough.

The only real risk I see is if your account is compromised somehow, but at least for me, there's nothing so sensitive in my account that I'd care.
