I wish I knew the precise steps. I've certainly wanted to rage quit FB in the past but I'd be socially isolating myself since I have friends that post there. Also, FB Messenger is my most used communication tool though I could use that without using FB.
I'd love to know what A-B testing, if any, FB has done here and if their methodologies for ascertaining results are actually correct. For example, it's obvious that the success of TikTok has them pushing "loops", one of their TikTok clone efforts. I'd personally like to completely block "loops" from my life except maybe if a friend recommends one, and I'd have a better opinion of FB if they let me. I can guess that might not translate to better metrics on 1 billion people but I can also imagine not annoying people would lead to more engagement.
I quit Instagram because it was ~1 relevant post (a friend) to 5+ irrelevant posts (non-friends) and their redesign to try to push me to follow non-friends by only showing non-seen friend posts and then filling my feed with non-friend spam. So, I quit. Is that a loss for them? No idea. I only know I'd have stayed if they let me opt out of the push to be TikTok.
