The fact that the Twitter hack wasn’t consequential further alienates the public from the risks of centralization in information infrastructure. Most Twitter users probably didn’t even notice the drama. As far as we know, the few who were hacked suffered limited ill effects. And the low-grade power users, like me, who were caught in the crossfire either got their account back and carried on as before or didn’t (yet) and amount to uncounted casualties of centralized communications.
The concern is about the implications associated with such platforms for manipulation.
