I don't really know why Google, a company, is doing what should be done by the government with no clear benefit to the bottom line. This is not to say they shouldn’t do this, but if you look at it that way, it shouldn't be surprising at all. If they really wanted to help they probably should have teamed up with the government to ensure that there is government buy in to the program.
I think Google is an insecure advertising company. It's as if Phillip Morris International was trying to develop solar panels and vegan food products to make everyone forget that most of their revenue comes from tobacco.
You mean Altria. They changed their name, for some strange reason.
