I did choose to work for Facebook. The pitch I was given seven years ago was that (1) the mission of the company is to lower costs of building community and connecting people; running an ad-funded social media platform is the means to that end. That's not a mission that is super important to me, but I can respect it. And (2) FB is the company that is investing heavily in advancing modern developer tools outside of the Microsoft ecosystem. That is a mission that is important to me.
Your statement that I wish I could continue to work for and enrich Zuck is false. I was regretted attrition.
Your lack of empathy is clear.
