I don't get the downvotes. This is a perfectly logical position. Looking back, the fall of the Berlin wall may seem predictable, but who would have forecast it in 1988?

Yes, I remember the 80s, and the USSR was one of those things you just assumed would be around for the foreseeable future, like marijuana prohibition (though for that one there was more of an inkling of possibility given more time). What you can say "within reason" depends on what you think everyone else thinks you can say, so equilibria are both really stable and subject to surprising flips when they finally tip over -- sort of like digital logic.

I wonder what we can do to prevent a segregated internet?

on small scale, consistently ignore and boycott all attempts by governments to do so. They are not allmighty, they cannot place an armed cop behind every single citicen. If you are in a country that has some functioning democratic institutions, you may also try using them

Also, work to increase the democraticness of institutions in your country so that it may be changed in the future, and work to change people's thoughts on matters so they grow the will to change things.
