I’m surprised that Facebook consistently ranks higher than Snapchat on these charts. I thought younger generations considered Facebook to be for “old people” for just about 7 years now.
It's just not true in reality though. I see people from young teenagers to people in their twenties and thirties using Facebook. It's dominant amongst all age groups and the "Facebook is for old people" trope is a myth that needs to die out.
I mean, you don't need Facebook to do any of those things you listed. People can still call, or text, or use a myriad of different messaging apps like Signal, Telegram, Viber etc.You don't need Facebook to find out about events or concerts and the like either.
You are correct, however the reality is more nuanced. Good luck getting any of the old people in my family to try a different app for messaging. You can set it up for them, but hoo boy, "fixing" it when they move it or something else is a full time job and not worth the effort.
I mostly use Signal and SMS for a few people. Facebook isn't worth it just for Marketplace. Online shopping isn't that important, let alone for second hand goods.
Yeah, apart from what another person said about alternative apps... Events organized by local communities or businesses are often advertised in Facebook only. I know of a few local businesses in my area with Facebook being their only online presence.
