$60M seems a lot to normal people, but what if Google earned say $61M with that practice, therefore they were aware it would turn as a gain for them? I mean, the penalty should be of course proportional to the offense, but prosecutors should also calculate in some way the benefits so the penalty works as a serious deterrent in the future.
Also, part of the fee should be compensation for the users involved, even if that would be a few bucks, as it's important they're made aware that they were lied to and how, so they can develop more resistance to false advertising or mistreatment of their personal data in the future.
