What would be convincing proof according to your standards? The complete implosion of democracy? The visible persecution of some minority? Tracing everything back via a proper legalistic paper trail to the actions of a single corporate entity? That's not how the road to hell is usually paved.

Who redefined "Terms and norms"? Who declared that privacy is dead? The problem really is that people have normalized a practice (surveillance, compilation of human behavioral profiles, classification, trading of such profiles, material impact on people's life based on such data and their algorithmic interpretation) that is historically the hallmark of oppression. This is not normal, not if we live in democratic, well functioning societies as we are led to believe. The cambridge-analytica episode is just the tip of the iceberg of what will happen if politicians and markets keep legitimizing this business model.

Why place this bomb under society? Is there any service being offered that is not reproducible otherwise? Its just some freaking databases and servers and messages after all. What the world is waiting for is for the gargantuan mea-culpa of silicon valley and the amoral capital that financed this.
