[D]epending on your use of Dropbox there are far better services. If you are simply storing and sharing files with a select few then Google drive gives you 15 GB which is a huge amount of storage in comparison.
Plus with someone like Rice onboard, how long before Dropbox ends up in an incestuous relationship with the NSA?
You claim to be concerned about "incestuous relationship[s] with the NSA," yet you recommend another corporate partner in NSA's PRISM spy-ring in favor of another. Why not find/try a tool or service that hasn't already been implicated in NSA-produced documents in serving as a front-end for one or more of their "collect it all" programs? In my view, that one of these corporate partners allows you to hand over more data to the NSA than a competitor isn't a compelling argument for its use — especially when that corporation makes their billions in part by scrutinizing and monetizing anything you give them in the first place.
15GB may be "huge" in comparison to another service willing to oh-so-charitably take ownership of your data for you, but 15GB represents a mere ~1% of a typical modern HDD, or about a seventh of what I upload daily via BitTorrent. Add in end-to-end encryption and a good-availability residential Internet connection, and you can share data without utilizing surveillance-state honeypots. For tools and services that allow you to do this, the website PRISM Break is a great place to start looking for a solution that has had at least some effort put forth in protecting users' privacy.
