I don't see how that would make any sense. Why would they do that? To me, it seems like Dropbox wants to sell storage to people, the more things that plug into Dropbox, the more storage they sell.

Twitter made a bunch of moves to limit third party integration because they need to control the channel so they can sell ads to be displayed on the platform, and display promoted accounts and tweets.

Obviously we don’t want this to happen, and I personally don’t think it will, but the Harp Platform has been built with this possibility in mind. The Harp Platform isn’t built upon Dropbox, we chose to make Dropbox one part of our interface.
