Dotcom was known for being good with the media, just because he kept a low profile for a while doesn't mean he changed there.
He was always in a shady area, but he burned himself once with a really illegal dialer and learned from it.
He is a player and never stops.
Looking at his history, nothing he does now is surprising.
They should have made a deal with him, buy Megaupload and hope he settles down playing CoD.

Pervasive SSL and VPNs seems to be about the best we can hope for now, and some improvements (like cert pinning). And we don't even have that, now, even though it's more than feasible.
Vendors have gotten better at OS level security, especially on mobile, but not in ways which help decentralization -- a lot of it actually pushes toward more security against small threats (hackers, thieves, etc.) but more vulnerability against the state or vendor lock-out.
