But SV doesn't get to redefine ethics. They have to confront the same problems, criteria, and choices as the rest of us.

For example, I used to contract to the US military in the DC area. That work invited many of the same concerns that SV does -- privacy, security, freedom of speech, acting preserve and defend the Constitution's principles. Today I work for a big pharmaceutical. Comparable concerns apply here too -- honesty, doing no harm, serving people in need, improving and extending their lives.

Ethics are universal, no matter where you live or what you do.
