How wouldn't they know? Claude Code is proprietary they can put whatever telemetry they want in there.
> how are we violating... anything? I'm working within my usage limits...
It's well known that Claude code is heavily discounted compared to market API rates. The best interpretation of this is that it's a kind of marketing for their API. If you are not using Claude code for what it's intended for, then it's violating at least the spirit of that deal.
And apparently it's violating the terms of service. Is it fair and above board for them to ban people? idk, it feels pretty blatantly like control for the sake of control, or control for the sake of lock-in, or those analytics/telemetry contain something awfully juicy, because they're already getting the entire prompt. It's their service to run as they wish, but it's not a pro-customer move and I think it's priming people to jump ship if another model takes the lead.
