The answer is clearly "never" --- the attitude expressed in the article leads toward totalitarian control over people's personal lives. Toleration, as Europe took hundreds of years to painfully discover, is the way you build a cohesive society around people who disagree. When you ban cooperation among people with divergent political opinions, you not only lose out on any positive-sum productivity gains from the interaction, but also intensify these political differences and turn them into real rifts in society. I am disappointed in the contemporary trend to invest imaginary "harms" and propose remedies that, in the end, boil down to persecuting people for their beliefs. Altman is definitely right about the social atmosphere in tech. Imagining that we should, say, ban contributions to an open source project from someone who also participates in 4chan is part of the problem.
