Schrödinger's Ayatollah Mojtaba Khamenei just banned Iranians from "committing anything that harms social cohesion."
Translation: The Iranian regime just invoked another bogus excuse to crack down on dissent.
Assessment
The ban defines no specific acts, which is the point. Any criticism, protest, or organizing can be painted as harming social cohesion, giving authorities cover to arrest at will. Watch which behaviors the regime actually targets under this rule. The vagueness is the crackdown's mechanism.
