Yes, it is happening right in front of our eyes. Most tools are neutral, but the way they are being used is often very wrong. A developer may work on an ethically neutral solution, e.g. a classifier, but it a manger who decides "let's use it to automatically ban user accounts." The developer may argue the solution is not ready for that and there is a high number of false positives. The manager accepts that cost. So the technical aspect is just on the surface, deep down it all boils to simple human greed and other egoistical motives.
