I think this is more common than some people realize. I haven’t used FB for well over a decade, but I know that despite people claiming that it’s dead amongst millenials and the younger generation, a ton of people still occasionally use it to stay in touch with some people and a ton of clubs, towns, businesses, etc still use it as the main hub for communication and FB marketplace is huge in some regions. Hell buying a used motorcycle was a little tricky without it, but luckily Craigslist is still going strong where I am.
I personally don’t care, but it would be foolish for me to say that I’m not missing local events and news by not using FB.
