I agree it violates trademark usage (also not a lawyer). But even if it is legal, it's still unethical, since they explicitly asked projects to not use their names in the doc you linked. And even if you believe it is ethical from some vaguely libertarian "'information wants to be free' means I should be able to do whatever I want online", it is still a bad idea if you actually want to work with the pandas team. If you need some PR to be merged into any numfocus project (numpy, jupyter, dask, among others) that only benefits pandas AI, I think they would be fully justified in letting it sit.
