Twitter makes it super easy to do mass warrantless surveillance, because Twitter gathers millions of people together in the same searchable public space. It's a honeypot.
What's dangerous about the "public square" concept is that Musk doesn't just want a public square — one public space among many, one among equals — he wants the public square, a monopoly on online conversation.

We shouldn't have all of our conversations, political or otherwise, in one place. That's a giant mistake. We need decentralization for our own safety and freedom.
