What makes Facebook bad is not "old people are cringe". That's ageist. I mean "old people smell"? Really? That's your subheading?
The privacy issues and the fucking algorithm that makes you addicted to it, is the problem with Facebook.
I was addicted to Facebook. I broke that addiction but it was really damaging my mental health before I did that. Not because of old people.
TikTok has the same problem btw. It's even MORE addictive than Facebook. Which is why I will never join TikTok.
