Poison the well. Everybody, anywhere in the world, whether it be a government, corporation, or individual, needs to become skilled at disinformation. If everybody's default behaviour is to muddy the waters by generating all kinds of contradictory data, the background noise level becomes so high that discerning fact from fiction is very difficult. Governments and corporations already use this tactic against the population; I consider much of Prime Time and 'reality' television to be propaganda, a kind of cultural disease vector.
Given that the genie is out of the bottle and privacy is dead, it would be best for everybody to know everything about everybody else, until the data becomes meaningless because of its sheer volume and commonness. If all possible information about what's going on is available to everyone everywhere, then it becomes essentially worthless. But the TLAs and corporations won't let that happen - they'll always be one up on mere citizens when it comes to info gathering. So maybe it's time for everyone to start sowing disinformation. That would make the world really, really suck; but it would probably suck a lot less than it will if the ultimate goals of Big Brother are achieved.
