I think you do:
According to the article https://www.perplexity.ai/page/anthropic-reverses-privacy-st...
"Enterprise and educational customers will continue operating under their existing privacy protections, as the policy changes specifically exclude Claude for Work and Claude for Education services. These commercial accounts remain governed by separate contractual agreements that maintain stricter data handling standards.
Organizations using Claude through business partnerships or educational licenses can continue their operations without concern for the new training policies affecting their sensitive communications or proprietary information."
Thus, I think your claim
> What a shoot your own foot business decision.
likely does not hold: the non-commercial accounts likely led to Anthropic loosing money, so they are not liked by Anthropic anyway (but are a an "inconvenient necessity" to get people to notice and try out your product offering). With this new decision, Anthropic makes this "free-riding" less attractive.
I bet that Anthropic will soon release a press statement (that exists in the drawers for quite a long time) "We are listening to your concerns, and will thus extend our 'privacy-conscious offering' to new groups of customers. Only 30 $ per month."
