It strikes me as exactly the sort of thing she should be writing given OpenAI's charter. Recognizing and rewarding work towards AI safety is good practice for an organization whose entire purpose is the promotion of AI safety.
On the other hand, its quite apparent that essentially all of the OpenAI workforce (understandably, given the compensation package which creates a financial interest at odds with the nonprofit's mission) and in particular the entire executive team saw the charter as a useful PR fiction, not a mission (except maybe Ilya, though the flip-flop in the middle of this action may mean he saw it the same way, but thought that given the conflict, dumping Sam and Greg would be the only way to preserve the fiction, and whatever cost it would have would be worthwhile given that function.)
