I see the argument that cryptos reduce the grasp of oppressive regimes on here pretty frequently but the truth is that a) the null hypothesis (no effect) has yet to be rejected with any data and b) oppressive regimes are very good at eliminating or severely restricting internet access when it suits them.

A slight tangent -- you can't just take two options and say we don't have any data so we can't judge. We have a prior: most things do not have an effect in this case.
