Snowden: "Google, Facebook, Microsoft, Yahoo, Apple, and the rest of our internet titans must ask themselves why they aren't fighting for our interests the same way". Indeed, they must. Your move Google, Facebook, Microsoft, Yahoo and Apple.
You mean: Your move Larry, Mark, Steve, Merissa and Tim. In the end the base unit of society is still the human, no matter how many layers we place around them.
A CEO/Chairman hurting a public companies profit via protest against NSA would result in shareholder lawsuits. Another good example of the the legal constructs around corporatism and public stock markets hurting the inherent protectionism from abuse free markets offer society.
Corporatism often prevents large companies from acting morally, whether by being protected from real repercussions for acting maliciously via being a single legal entity (resulting in mass settlements not individual employee liability) or their legal obligations to only care about short-term profits (post-IPO), not long term gains or societal benefit.
