[contingencies]

You are right to draw attention to Facebook, but personally I live in China where it is blocked (a very intelligent and forward-looking Chinese government action, in my view) and rarely mentioned so I don't feel informed to comment on it's recent changes: the last time I touched it was perhaps 6 years ago in order to remove all vestiges of media from my account, then to remove my account.

It is true that there are larger manipulators of public perception - look at Hollywood - and I do think the same concerns should be leveled at them (eg. US military sponsorship and support for certain pro-US movies, product placements, etc.).
