The most ubiquitous, absolutely. Their data collection is unparalleled. They're on almost every website, app, they have fingers into payment and browsers and mobile OSes.

In terms of what they do with big data there's more evil parties like Palantir but data abuse starts with collecting it, and I would object to it even if Google promised to only use it for good. For me my privacy is already violated when my data is collected, not just when it's abused. And I do consider Google's use of that data abusive, just not in the worst ways.
