I am saying that tech execs have no special knowledge, and their actions should not be used to inform one’s own opinions or social policy on the topic.

There IS tons of data in this area. Please, do yourself a favor and read it (pay attention to the population of studies —- many use adults in their 30’s or older as proxies for children).

You can absolutely find real data supporting your position. And it will be more persuasive (albeit less dramatic) than imagining what Altman probably does.
