The real truth is this poll is not a representative of regular dropbox users. Vast majority of them don't care who is in the board or even at the helm of the company. For many the thing that matters are whether the product works for them or not? Are they getting the value for their money? Switching costs . Etc..

Undoubtedly dropbox has one of the best offering in this space. It is highly unlikely for anybody to dislodge them.
