The data is a privacy issue because we have an enormous ecological disaster created by badly-designed social media now being used by people to control and exploit human beings in all sorts of ways.
That’s the consequence of social media structures which encourage people to share using centralized databases, and everything they share is held by someone who is no friend of theirs who also runs the servers and collects the logs which contain all the information about who accesses what, the consequences of which is that we are creating systems of comprehensive surveillance in which a billion people are involved and those people’s lives are being lived under a kind of scrutiny which no secret police service is the 20th century could ever have aspired to achieve. And all of that data is being collected and sold by people whose goal it is to make a profit selling the ability to control human beings by knowing more about themselves than they know. Okay? That’s true of all this information all the time everywhere. The thing you’re working on is simply one of 100,000 implications of that disaster.
