You'd be surprised that there are still (technically competent) HN users who seem to be that naive. Or to promote gv't propaganda.

Our only solution is to go 100% open-source and 100% end-to-end encryption.

And the government has the power to ban open source and encrypted communications. It's not really all that difficult, if you eliminate any concern for the constitution. If all else fails, rubber hoses and bullets work well.

That won't work. People will just do it anyway. Just look at how well alcohol prohibition worked.

That's part of the beauty of open source - once the cat is out of the bag, there is no getting it back in.

Many decentralized projects really give me hope for a secure and private internet. Though there are still big problems with those systems (e.g. sybil attacks and what not) and general adoption rate.

But you do already see block-chain technology used by huge industries like for diamonds and projects like ZeroNet are surprisingly user friendly and visually pleasing (though sadly most zites use a centralized identity authority.)
