As the article appears to be AI-assisted and isn’t clear about their source (despite alleging they have high editorial standards), here it is:

Some passages I found relevant:

As outlined in OFAC’s FAQ 1190, the United States does not sanction persons for engaging in political speech or other constitutionally protected activities. As outlined in E.O. 13224 of September 23, 2001, however, “violent acts and acts dangerous to human life, property, or infrastructure, that appear to be intended to intimidate or coerce a civilian population, or to influence the policy of a government by intimidation or coercion” are defined as terrorism.

In 2001, we decided “the appearance of coercion to change government policy” was terrorism. That checks out.

Autistici Inventati identifies itself as an “anti-fascist” and “anti-militarist” organization opposed to capitalism and exclusively provides its services to vetted individuals, collectives, and groups it perceives to be aligned with its ideology

Can terrorism even be terrorism without militarism? Oh right, coercion. My bad.

Oregon-based Rose City Antifa has relied on A/I Collective tools and services to organize and incite violent and criminal acts domestically, including an attack on Customs and Border Patrol helicopters that led to a federal indictment. Rose City Antifa also used A/I Collective tools and services to disseminate doxing lists and release illegally obtained personal information of Federal Immigration and Customs Enforcement, along with calls for targeted attacks on ICE agents in the streets and “in their homes.”

Seriously, what are they talking about regarding the helicopter thing and the alleged “calls” - the only reference to helicopters I can find is an alleged flyer that’s now locked behind a Twitter wall. It’s not on Wikipedia.
