> they could easily identify abusive users and throttle them specifically.

that's exactly what they've done? they've even put rough numbers in the email indicating what they consider to be "abusive"?

That’s bs. I just switched from 100 EUR a month to 200 EUR plan. Why? Because two days ago Anthropic decided that I had to wait until noon. And I just started my workday and used CC for half an hour.

I use CC 1-3h a day. Three days a week. Am I a heavy user now? Will I be in the 5% group? If I am, who will I argue with? Anthropic says in its mail that I can cancel my subscription.
