Any company that can censor will eventually be pressured by governments (or its own employees) to do so. Therefore, I see Signal as a model for how everything should operate in the future: your "account" in the company's database is just an encrypted blob that they can't read. Is there no way to make a Twitter-like broadcast messaging app work on top of a Signal backbone? It'd take a smarter programmer than me to figure out the details, but it's got to be possible, right? I mean, right now we have several well-accepted cryptocurrencies that I can use to send an uncensorable, untraceable payment anywhere in the world for about $5 in fees. It's a bit clunky, but it basically works. Why can't I post an uncensorable tweet for $5, too?
