This is not what I am saying. What I am saying is that there are plenty of people in countries doing illegal-on-paper things but are largely ignored by their Governments. No one in Brazil is worried about torrenting, even though it is not legal. No one connecting to a Swedish VPN provider worries much about getting copyright infringement letters, and so on. No one in Russia is worried about downloading music via VK, a social network with more ties to its Government than Facebook with the CIA.
> software should maintain privacy by default (...) you should treat this like reporting your downloads to your Government voluntarily.
I don't see any contradiction between what you are saying and what I am saying.
Yes, it should be secure by default. Yes, people should be aware that anything that is not sent encrypted and securely should be considered public knowledge.
So what?
Nothing of what you said negates the fact that there is a huge number of use cases where people want things to be public (Youtube? Instagram? Basically every social network?) and that they will benefit from having it that way.
You might not care about these use cases because you are too risk-averse to use them. Fine. There are plenty of other people who are totally okay with these risks. As long as they aware of the risks, why stop them?
Worse still, between a system that does only one thing "super-privately" vs something that gives them privacy when they want it and also gives them "things where I don't care if is public or not", which one do you think people will use? Look at another post on the same thread, you have people sharing multi-GB Anime over IRC, ffs.
