It seems Anthropic has taken an aggressive stance on their buffet, flat rate plans being used in any tool not created by them, where they immediately ban such accounts.

I believe they still allow API usage in this manner though.

In this case, the OP attempted to use Zed with Anthropic's $20/mo plan and was banned immediately. I imagine if they had went the API usage route, this wouldn't have transpired.

Surprisingly, I wonder if this will push more people to use Cursor because they allow you to use a variety of models, including SOTA. That, or manage your own API key subscriptions with a middleware like LiteLLM that also monitors usage so that your coding frenzy doesn't turn into a $20k bill. Or maybe OpenRouter where you manually top up the account.
