Yes, in the sense that Facebook app is probably the biggest single app
in mobile and probably has about the most users. Advancing the
transport layer, especially with regards to security and privacy, is
critical to maintain long term viability. But that being said,
security, protocol ossification, middlebox intrusion, the demise of
the E2E model are everyone's problem. One major issue here, probably
the biggest issue on the whole Internet, is that upgrade story for
core software (FW, OS, etc.) in devices attached to the Internet is
miserable-- to the point that some people think this undermines the
future of the Internet (e.g.
http://www.darkreading.com/vulnerabilities---threats/internet-of-things-devices-are-doomed/d/d-id/1315735).
TOU is a means to eliminate the dependencies we have on devices or
OSes being secure or being updated in a timely fashion to provide
security improvements.
