I kept Dropbox because they appointed Rice. Dropbox is forced to navigate complicated political, regulatory waters. To do that successfully you need someone who knows how they works. People move from the public to private sector all the time to do exactly that.

Yes. What do you think happens when a public official transitions to the private sector? That they are a plant still serving their old employer? Or, perhaps, that they are applying skills and knowledge learned in their old job to a their new role for a new employer?
Just don't get confused about who Condoleeza Rice is working to support. It's not you, the user, it's Dropbox as a company.
There are many decisions that Dropbox will have to make which will not be in your favour but will be in theirs. If you're lucky, they'll even tell you about those decisions.
