I think it's a mistake to think that the tyrannical governments of the future will be sophisticated. The way the trend is going, they will be ever more banal. They're not going to target a virus for you, they're going to knock down your door, shout at you, lock you up or shoot you. They likely won't even bother with having chatgpt write up a pretext for it.

That doesn't mean we can do nothing, but it means withholding information won't matter as much as some people think.
