Google was fined billions for outright illegal practices and is mostly concerned about power, not illegality.
Furthermore, in hierarchical structures people only care what those above them think. "Illegality" of the feature is something for lawyers, not them. At best they rely on morals, but even that is screwed by perks, incentives, the environment they work in, peer pressure, management, corporate propaganda, etc. Generally in such structures you can make people do anything, even kill other people and be ready to get killed.
I dont think Google was fined billions over privacy violations, just antitrust ones and only in the EU. In the US Eric Schmidt's constant lobbying to Obama got them off the hook for the antitrust investigation even though the FTC staff investigating their violations recommended antitrust action against Google.
