I strongly disagree.

Politicians: technology that strengthens the power of the state, against crime, but also militarily, for spying on enemies both foreign and domestic.

Citizens: defensive architecture that prevents the state from preventing free speech.

This is especially relevant in the era of AI, where the cost of mass surveillance is virtually zero, and is incredibly powerful at sentiment analysis and summarization. Free speech is threatened when any statement can and will be used against you.

also politicians want a backdoor especially for tracking treason / spying possibilities, which in a way comes under police investigating crimes but is more national security apparatus protecting the state.

Which makes no sense, because if you have a backdoor, it opens the way for adversaries to access your data. You don't improve your national security by weakening its encryption.
