This is my question too. I’ve never used Facebook, yet I’ve never had any trouble finding the information I am looking for. Is it just very very specific places?

A lot of small businesses in the UK seem to use Facebook rather than putting up a web page. I can see why they do it, it doesn't cost anything and they don't need to worry about renewing domains or hosting issues. It's not a great experience for their customers though, especially if you don't have a Facebook account.

My local ferry https://www.libertylandingcityferry.com/ only has its service updates on FB https://www.facebook.com/LibertyLandingFerry

I didn't have facebook for the last few years and I was wondering if I'd have to come back to it to be able to access local news/info. Never happened and never needed to. It's true though that in some countries that's the primary communication channel for businesses and even governments unfortunately.

It's possible you're not in the same market as us. Lots of small businesses have no interest in running and updating a website, especially when there's a free alternative that most of their customers have access to.
