Google is a megacorp, and while megacorps aren't fundamentally "evil" (for some definitions of evil), they are fundamentally unconcerned with goodness or morality, and any appearance that they are is purely a marketing exercise.
A couple years ago, my state banned single use plastic bags. The very moment they did, all of my local Walmarts switched to heavier plastic bags that technically weren't single use. They still gave them away for free just as they did with the first ones. (These we're good quality bags and I was frustrated that Walmart didn't just give them away by default). Eventually my state banned those too, and like clockwork, Walmart was giving away paper bag bags -- decent quality ones, too. Though I still really liked the thicker plastic ones since I could use them for other things.
This made me realize that no corporation would do anything slightly better for the environment unless forced. I think this is the case for anything a corporation would do, including evil things. I think they just follow the money, no ethics, and it's up to the government to provide those ethics.
