I read that as a cynical view of the motivations of corporations, not humans. Even if individuals have good faith beliefs in "AI 'safety'", and even if some such individuals work for AI companies, the behaviors of the companies themselves are ultimately the product of many individual motivations and surrounding incentive structures.

To the extent that a large corporation can be said to "believe" or "mean" anything, that seems like a fair statement to me. It's just a more specific case of pointing out that for-profit corporations as entities are ultimately motivated by profit, not public benefit (even if specific founders/employees/shareholders are individually motivated by certain ideals).
