Technical solutions are the only possible answer, that and cultural responses.
Vast state surveillance is made possible by technical expertise. We shouldnt laud those who assist the government in this task nor in any tasks. We should shun colleagues who choose to assist the enemies of humanity, those in positions to hire should not hire those with backgrounds in government and make it known through back channels that such people are not desirable, that you will be black balled if choose to assist these heinous entities in their oppression.
Finally those able and willing should consider other methods of raising the cost of state surveillance, but openly recommending such things is potentially a crime in the eyes of the state.
