Your post seems to imply that this is some sort of conspiracy by local politicians but that's probably disinformation itself:

From the article:

A fusion center in Philadelphia combed through spicy Internet comments from AI critics and concluded there is a growing risk of physical violence against data centers from "domestic violent extremists", ranging from white supremacists to anarchists.

From Wikipedia:

In the United States, fusion centers are designed to promote information sharing at the federal level between agencies such as the Federal Bureau of Investigation, the U.S. Department of Homeland Security, the U.S. Department of Justice, and state, local, and tribal law enforcement.

It is much more likely that the federal government had an algorithm flag these comments and sent them to Philly law enforcement for review.
