None of this is science or evidence based, it's political theater. The labs do this because the government has made it clear it will intervene if they don't say the line. I suspect most of the people at the labs think AI watermarking is a retarded approach.

The people that make the laws and the people complaining about AI don't know or care about the reality of the situation nearly as much as they care about being re-elected and feeling good about their social posture.
