There's one trust issue I have with Dropbox though, which goes by the name of Condoleezza Rice. Since 2014 she's been serving on the Dropbox board of directors.
While Dropbox probably approached her because she undoubtedly is a very talented woman and not because of her political background the agenda implemented by the administration she was part of, particular the surveillance measure, leaves a sour aftertaste.
As a company for which protection of user privacy rights should have paramount importance how do you justify hiring someone who obviously couldn't care less about these rights?
