When I look at Facebook, my feed used to be 99% stuff posted by my friends and family. Now, it is only about 20% stuff posted by my friends and family.
It's dangerous to go alone, take this.
Also, never use the app. Not only is it fucking stupid in general to trust Facebook to run code on your phone directly (it's not great in the browser either) but a prior version of their app copied everyone's contacts and then DELETED THEM FROM THEIR PHONES so we know conclusively that using the app is a shit plan.
The moment they started chasing engagement instead of users was the point when they became a net harm to society.
The original goal of Facebook was for Zuckerfuck to make engagement with women by tricking them into trusting him with misuse of their PII.
