I think each of the four examples I mentioned did have a long-lasting effect on the company as well, e.g. the Data Liberation Front ( http://www.dataliberation.org/ ) is a natural result of the pledge not to trap users' data.
I continue to have concerns about Google, but at the same time I continue to perceive a culture where people stand up and advocate for, insist upon, or just quietly do "the right thing".
(Now, where's my green energy flying car. ;-)
P.S. I guess I felt this worthy of a comment, in that I continue to struggle with my own interpretation of this dichotomy. And I don't think I'm alone.
