Technically, I agree, but there is a sizable range of opinions where reasonable folks can agree to disagree, and produce good work. The set of people holding opinions in that range is larger than some of the commenters in this thread seem to believe.
That's another issue, my point is that this isn't new. Business have always had political postures and actions, the only different thing is that the illusion of Silicon Valley being "neutral" isn't working anymore.
I think that range ebbs and flows over time, to be honest. I'm not American, but it seems like there was less polarization in the US the 1950s than there was in the early 1900s, for example.
I don't think it's unfair to not assume some "happy median" will always be there or a certain size, especially as circumstances change over time.
