Anthropic, OpenAI, Google et. al. have EULAs and the best lawyers money can buy ready to argue that any damage done by publicly releasing bad or malicious code produced or reviewed with their systems is the developers responsibility for not checking properly.

Given the vendors EULAs etc, if poop really hits the fan with released code, then how is that likely to sound if the lawyers get involved?

> Are people still reading PRs in detail manually?

Ultimately it all depends on circumstance and appetite for risk, but yes many/most places still manually checking releases.
