OpenAI didn't fall for anything, they knew exactly what they were signing and went ahead anyway, then started gaslighting people about what they had signed.
For a lot of people (me included) the lack of integrity and the gaslighting is what has soured them on OpenAI, rather than them signing up to build surveillance and weaponry.
To non-US citizens, all AI companies are as dangerous as each other, OpenAI just really botched the optics here.
