Now that I think about it, advertisers go against themselves when they both push useless shit and collect usage data.
Like, if I keep accidentally clicking on an ad app, and the telemetry shows that I keep clicking on it, then the conclusion might be that I love that particular app?
Well, and the separate app telemetry shows that it always runs for 3 seconds before being closed, so the conclusion is that it needs to be pushed and advertised more?
