Thought there were some good points in this piece, particularly:

It’s true that tech makes finding these conspiracy fantasies easier than ever, and it’s true that tech makes forming communities of conspiratorial belief easier, too. But the vulnerability to conspiratorialism that algorithms identify and target people based on isn’t a function of Big Data. It’s a function of corruption – of life in a world in which real conspiracies (to steal your wages, or let rich people escape the consequences of their crimes, or sacrifice your safety to protect large firms’ profits) are everywhere.
