This is a complete nothingburger article that’s just repeating Tyler McVicker’s speculation. I like McVicker, but to act like his guess is insight from a “Valve insider” is dogshit-tier journalism.

From The Guardian article on the same incident:

The defendant, Sam Tunick, was stopped for interrogation at Atlanta’s Hartsfield-Jackson airport on 24 January last year, after vacationing in the Dominican Republic. Unbeknown to him, federal authorities had put him on a terrorism watchlist because of his alleged association with the movement against Cop City.
