As much as I hate to admit, I do agree with Thiel's point (barely mentioned after the first paragraph) that the vast majority of thought is being driven by politically intolerant left-leaning liberals. I am absolutely one of them, but it's amazing that in multiple major tech companies in Seattle, there has been a near-100% shared liberal mentality, that has only exploded post-Trump.
It's very difficult to make products and apps for everyone, when the people making them represents only one viewpoint. And interestingly, unlike companies that localize/culturalize their products by opening local offices, I don't know of any companies opening satellite offices in Alabama/Mississippi or even conservative counties in Washington and California.
I remember when it used to be taboo to talk politics in the office. I find that doesn't even exist anymore, when everyone shares the same left-leaning mindset.
