That's exactly right and what people complain about. That Dropbox betrayed the trust they(users) were giving to them(Dropbox).

I don't necessarily agree with them, but that's the sentiment here.

Edit: by the way, regarding open source projects, it doesn't matter if you don't look at the code personally. Somebody else does, and if there is problem with it, it becomes a huge public scandal sooner or later.
