You should be able to "archive a group as admin, which essentially shuts it down. I haven’t tried but I’ve seen it happen in other groups. And yeah, it’s really disturbing what people will accept from FB for the sake of inertia and comfort. I’ve told a couple friends about Meta using the localhost loophole for tracking and recommended they delete the apps and just use the web version if they need to, and they all still have the apps. Who even needs privacy, right? Sigh
