I wonder how much that contributed. No matter the personal political leanings of the employees, most companies try to stay on the good side of both sides of the political aisle. When the president of Heritage Foundation (which is about as close to establishment conservatism as possible) was opposed so vehemently, it really created a rift with conservatives and now there are Republican Senators who now are calling for Google to get reigned in. The business leadership can’t be too happy about that.
This is an impossible task. My opinion is that Google should support its employees and deliberately position itself against the right. No matter how much ground you concede to them, they're going to act in bad faith anyway, so why listen to them at all?
