Apparently they provide the digital infrastructure for violent Antifa cells and because of a 9/11 related executive order, the A/I is able to be branded a sponsor of terrorism.

EDIT: who is downvoting and why? The 2nd sentence in the PR says "Autistici/Inventati (A/I Collective) is an Italy-based extremist group that builds and operates the digital infrastructure for violent Antifa cells and other far-left militants across the world" Are you mad that I quote the article or mad that you disagree with Trump? In either case, why are you downvoting me exactly? I am genuinely curious.
