I'm not saying those trends charts demonstrate anything, just that commercial human astro-turfers or bot networks are no less of a thing than intelligence ones and it wouldn't really be a conspiracy theory to think McDonalds or any other company, trade association, lobbyist, PR firm etc, is operating a lot of social media accounts that could theoretically show up on a report like that if they were doing a lot of it from a specific place.
Eglin has something like 50,000 people but it's actual population as a census designated area is more like 5000.
Oak Brook, IL was also "most addicted" but people didn't run with the idea that McDonalds HQ was running psyops.
