(It was one of the first significant value-adds of GMail: at its scale, Google could create a global-concept understanding of the content and pattern of spam across hundreds of millions of users. That was the kind of Big Data that made it possible to build filters where one could confidently say "This is tuned on all spam in the wild, because we've seen all spam in the wild").
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."
And - this behavior of Google's has not been penalized, I'm afraid.
Certainly not for any users like you and me, it takes two seconds and three clicks to review the new terms and decline chat training. This is more like Anthropic getting easy training from people who are unaware or don't care.
But also, Anthropic has said that this new policy also applies to their Pro ($20/mo) and Max ($200/mo) plans. So its not free versus not free.
Oh the naivety.
Sooner or later they all become the same, soon after "investors" or "shareholders" arrive.
Companies are less like people and more like bacteria. They are programmatic, like algorithms.
What they will do has already been decided for them, programmed into them, by the rules of capitalism. It is inevitable. There are no good guys, and there are no bad guys, there's just... microbes.
Those who do not engage in capitalism, perhaps they do not seek money at all, have no such hard limitations. But they are rare, because money is blood.
