I would assume users who have an existing subscription will be grandfathered in.

It would seem misleading to sell monthly, or even yearly, subscriptions under the guise Claude Code comes with the subscription, for it to only be yanked out underneath you. (Although depending who you ask, Anthropic have already done actions similar to this).

I was billed $220 on Mar 1 for the pro plan

If they rugpull Claude code from my already paid for annual subscription I’ll have to issue a chargeback
