Copying over my comment from elsewhere in this post:

Anthopic choosing to delay their models' invevitable distillation by competitors is their prerogative.

That they choose to implement it by fingerprinting my access patterns without first disclosing is where they shit the bed. It isn't "sneaky" it's straight up sneaky (and dishonest and unscrupulous while we're at it). That this particular instance is harmless doesn't give me much comfort. Who's to say they aren't harvesting PII?

That their actions make sense for their business isn't any reason for people to accept their deceitful, customer-hostile decisions.

Does their user agreement say they won't be harvesting PII?

> by fingerprinting my access patterns

It's based on whether your timezone is in China and your hostname matches a blacklist. Literally 2 bits of information. Not much of a fingerprint.

That's what it's based on right now, anyway.
