No matter how you feel about the situation, the law is pretty clear that colluding to limit R&D with your competitors is anticompetitive. The fact that these CEOs have called for this in public is pure arrogance enabled by horrific legal controls within the companies (OpenAI's blog post about the Apple lawsuit points to this too) or they're so confident about the degree of corruption in America they feel they can act with impunity. Either way we desperately need the rule of law to do its job and deter these antisocial behaviors.
