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.
I don’t disagree. I’m just saying, it’s still incredibly popular. I don’t even have an account myself.
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 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.
