I think the implication here is that if we can’t find evidence of or motivation for companies paying to inflate their star counts, then we should cool it on the accusation that magically fraud has appeared in this case.
We also should remember that if this project had zero stars, we would hear crowing from these same people about how true and important that metric was. The idea that “open claw” paid for these stars somehow is mostly just reasoning backwards from the idea that no one would find this project interesting.
