Anthropic just legally threatened Opencode to make them drop support: https://web.archive.org/web/20260221041617/https://github.com/anomalyco/opencode-anthropic-auth/pull/15#issuecomment-3930558874

In short, Anthropic only wants you using their official walled-garden clients to access the models trained on our open source code.
They are not a lesser evil. They are just as evil as OpenAI.
Stop giving these assholes money. Rent or buy hardware to self-host with privacy and freedom. It is not that hard, I promise.
