The words clearly don't mean nothing. They would mean nothing coming from someone who was not in a position to learn what someone who had worked in the industry has learned. They would mean nothing coming from someone who was being paid by someone who stands to gain from them. The fact that they come from someone who was paid to work in the field does the opposite of make them 'mean nothing'.

I agree with this take generally, but I also think it’s a gradient, not a spectrum. I think they claim that OpenAI is not considering safety and has become bad, not that AI is bad. Seen from a different lens, the author no longer stands to profit from OpenAI, so they’re empowered to speak openly. Plus, if I was going to say bad things about a former employer as powerful as OpenAI, I would want to have lawyer money handy.
