Google's internal training emphasizes to do the right thing and compete fairly%, going so far as to not use terms in PR or even internal email such as 'crush the competition' 'dominate' 'destroy', and always doing what's good for the user, rather than bad for the competition.
There's nothing altruistic about that. Emails with those words will cause problems for the legal department when they come up in discovery during antitrust litigation.
Google forcing their employees to go through training to avoid bribery, sexual harassment, and antitrust problems for the company is not due to anything other than saving the company money. To be pedantic, the disagreement with GGP is not whether the actions are altruistic but whether the actions were done out of altruism.
It's easy being altruistic when you're the clear leader and have a comfortable margin. Doesn't give me any comfort knowing how benevolent Google is presently.
