Amazon and Microsoft have never codified in their value system anything that touches “never working with the military” and no one that joins either company should or does have the expectation that the company would ever back away from something so lucrative.

Google on the other hand has created a culture of “do no evil” (even if that isn’t their official motto anymore) that encouraged SJW-ism, and thus falsely gave the impressions to their workforce that they could speak up about socially progressive issues that have clashed with corporate strategy. They’ve created a workforce of snowflakes, for lack of a better term, and the cognitive dissonance created by a fake progressive culture is extremely counter productive.
