Look up the story of Mamdouh Habib. It's really sad, he was tortured physically and mentally, labeled a terrorist and was released without charges by the USG after 4 years in detention.
Nope.
Actually turned out not to be such a bad thing as it forced me to rethink an implementation approach (using Dropbox APIs) that had seemed like a good idea, and was getting really sticky.
Not just a boycott, but I simply have no reason to use Dropbox. It's more expensive, does nothing Google Drive can't do, and on top of that, has all the political issues.
And one of the Dropbox board members was an ardent supporter of this and other despicable practices(also known as torture).
If Daniel Levine is fine with this, then I am definitely not fine with paying, using or promoting his product API.
edit: I switched to spideroak and am quite happy with the product.
