"Us tech people" are the ones enabling them to censor though. From the article: "Facebook this year removed 159 accounts at Vietnam’s behest, while YouTube took down 4,500 videos, or 90 percent of what the government requested".
When I say enable, I am talking about stateless nonprofits creating platforms where people can communicate freely, express themselves freely, and if they need to - organize protests to protect their freedoms. Things like Signal are great steps toward it, but we need more.
