You are right.

This just reads like a rancorous rant.

In any human group there will always be issues on how we treat each other dependent on time/context/culture. But while not condoning it, this issue is orthogonal to that of misaligned AI.

The communique from the mathematicians when shorn of polite language is blunt viz.

AI companies are stealing our hard-won lifelong research findings, which we were already sharing freely, without attribution/credit and building upon them without informed consent nor compensation.

The above is true for "misaligned AI" in all the Sciences. It is time the Scientific Community got together and sued the hell out of the AI companies.
