I am a happy paying customer of Dropbox, but the news that you have 
appointed Condoleezza Rice to your board is extremely disturbing and 
I will ditch your service if this decision is not reversed. 

Dr. Rice defends warrantless wiretapping. How am I supposed to trust
Dropbox with my personal files if your management cannot understand 
the implications of this appointment? And if they do understand 
-- which may well be the case -- then I am very sorry I ever shared 
any of my files with you.
