Let’s be clear: Google is participating in the prevailing business model for internet businesses in Silicon Valley. So in that sense, they’re not more evil than any other business that seeks to make money through personal data. You could also make the argument that they’re not as directly harmful as a company like Facebook, whose data practices have been shown to have undermined democracy in countries like the United States and Britain, and even to have supported genocides in countries like Myanmar.
However, the impact of Google’s business is exponentially greater because of its size. From widespread location collection in Google Maps, to the fact that the majority of sites on the internet host Google tracking code, it’s very hard to not be tracked and profiled by them in some way. That information has the potential to be cross-referenced, together with offline information like credit card purchases, which it adds together to create a highly targeted profile.
