The mass surveillance that these ad networks perpetrate has grown into grotesque proportions. One of the concerning "side effects" here is that it provides the basis for mass surveillance, repression and therefore authoritarian regimes - and a slide by democratic governments into a gradual increase of authoritarianism. It needs to come to a stop, and GDPR isn't going to accomplish that. But what solutions are out there that guarantee reasonable anonymity, and not at the same time provide a haven for criminals? My impression is that there aren't any, at least not sufficiently user friendly ones. Which means that there is a business opportunity here.
