I agree that your example is extreme. But I think that its extremeness invalidates it. There's a big difference between immigration and employment. Many families depend on a single country's immigration policies to be together. People who are barred from one company can seek employment at another company.

David Sacks' move is personal, and moves made out of frustration are often hypocritical, and I'm not surprised it's going to piss some people off. I'm glad this is just one person and one medium-sized company. If Apple, Microsoft, or Google announced this type of policy in a press release I'd be disgusted. It's easy for me to shrug it off when a CEO of a company with fewer than 500 employees announces it in a tweet and quickly waters it down significantly. https://twitter.com/#!/DavidSacks/status/179788086862028800
