We implicitly endorsed democratic movements like the Arab Spring by highlighting its use case, but you'll have to forgive me for going with a use case that is more likely to get media attention. The Arab Spring use case is stronger than you are letting on. Privly can facilitate group encryption keys, where only the members of the group can read or share the content. This allows the use of applications like the Facebook event system mashed together with email invitations and public tweets. Most people don't know how to use PGP, and group coordination is difficult without an easy to use and ubiquitous secure sharing system.

"if you don't want facebook to own your content and personal information, don't give it to them in the first place." Agreed, but they can have my links.

you didn't keep this apolitical at all. i only talked about an arab spring because you did so in your video. and i agree that your platform doesn't add any value for this kind use case, except the ease of use maybe, which i think isn't really a concern if you're operating in the political underground.

if you don't want facebook to own your content and personal information, don't give it to them in the first place. this is obviously easer said than done. but your service creates just another dependency while solving nothing.
