I think Larry (not, not that Larry, the other one) spilled the beans in 2024:

"Citizens will be on their best behavior, because we’re constantly recording and reporting everything that is going on" - Larry Ellison

(I seem to recall from the context of the quote, he isn't saying this is the future he wants, but it's a future he's not particularly opposed to)

But the real threat is "accidental" database leaks from private websites. Let's say you live in a state where abortion isn't legal, and you sign up for a web forum where people discuss getting out-of-state abortions. As soon as that website is required to collect real names (which it will be), it becomes unusable, because nobody can risk getting doxxed.

Maybe the US gov needs more tor users and is therefore doing this to drive more traffic to the onion network.
