I think Mr. Altman is largely addressing tech CEOs here and urging them to make public statements. The actions you list are great for you and me, but he's mostly not really talking to us.
Supporting quotations from the post (because evidence):
"The tech community is powerful. Large tech companies in particular have enormous power and are held in high regard. We need to hear from the CEOs clearly and unequivocally"
"At a minimum, companies should take a public stance."
