Do you have a citation on this? I have a Claude Pro subscription and looked at the comparison page and it says this under Pro: Everything in Free and: Claude Code directly in your codebase Power through tasks with Cowork Higher usage limits Deep research and analysis Memory that carries across conversations
It was recently discussed in https://news.ycombinator.com/item?id=47855565
Go to the pricing page: https://claude.com/pricing
As of right now, it says Pro includes Code and Cowork. (At least, for me. There could always be A/B testing going on.)
There is A/B testing going on and for a while several pages on Anthropic's site did remove Code from pro (https://old.reddit.com/r/ClaudeAI/comments/1srzhd7/psa_claud...) if you want a lot more details.
