Actually, I read today that both Hungary and Poland are setting up free speech sites on their own. Take it with a grain of salt, but I trust them more than Russians.
I don't know what Hungary is doing but I know that Poland is passing laws to fine social media for violating free speech. The problem is how will they enforce it? Jack Dorsey isn't afraid of President Trump, he certainly isn't afraid of some judge in Poland and I imagine he'd simply ignore any ruling against him.
