To be honest: you can still make your own website, and in many ways big companies are actually making it easier through open-source projects and stuff like Let's Encrypt. The web industry is remarkably open compared to what big companies do in other industries. A lot of the standards meetings and stuff you can just go to and give your opinion. Or ignore the standards and fork it yourself. This alarmism I fear will make people not take the actually alarming things like encryption bans or ID requirements seriously.
