Are you forgetting or not aware of security issues with Dropbox where a bug made passwords optional for four hours[1], some people claiming that it's not secure by design [2], and mislead customers about security policies [3]. I don't know how relevant these issues are today, but you're claims make it seem like that have a perfect record.
Hey mangodrunk. Thanks for taking the time to put together citations. I was aware of the first item on your list and I was impressed with how Dropbox handled the situation. Everyone have bugs, but it's how you deal with these things that speak volumes to me.
I haven't heard of the other 2 things on your list, but I'll take the time to read them thoroughly. Thanks for bringing them to my attention. Obviosuly privacy is something important to me, so knowing all the facts is important.
That being said, when it comes to TOS, Dropbox is far more attractive.
