Anthropic is facing criticism over its long-running anti-open-weights stance

The post points to a blog criticizing Anthropic's stance on open weights: the company did not sign an open-source petition that many large AI companies signed, has never released an open-source model, and is seen as generally unsupportive of open-source AI.

It's framed as a company-position issue rather than a model announcement: the key topic is Anthropic's long-running posture toward open weights and the broader open-source debate in AI.
