I did write an essay but this is the TLDR.
Google has made a giant political mistake. Everybody saw this coming. Straight into the fire, Google must have known that even as they did it.
If Google's real aim was non-talent-bias, we already know the solution: blind hiring.
Let's use a little metacognition here. People on HN are highly likely to be in the Bubble (same way as average academic must be left of center). They belong to the Valley and will rationalize these kinds of events all day long, it's worthy of "Let a Hundred Flowers Bloom!". Rightists are penalized in SV. That's been true for a while, that is the bottom line. This forum itself used to contain more rightists.
I don't know the future for Google or SV but the upshot is that if I found a company it will explicitly not hire leftists. I will have internal cohesion in my mini one party state. Do I want "diversity of ideas/perspectives". Yes, but the atmosphere is already poisoned by events like this and the firing of Brendan Eich. Plainly nobody has the right answers so I'd opt for political uniformity to keep infighting at bay.
More broadly I suspect Affirmative Action is on the ropes which means that SV is way behind the curve.
tldr;tldr; Somebody as brilliant as Peter Thiel would be fired today, or more likely: never hired. That is where we are at.
