It's a fact of life everything eventually declines and humans get bored easily ten years is a long time and things move on. Combine this with all the negativity you have mentioned. You end up with a atmosphere and environment where many people feel betrayed. I reluctantly joined Facebook, because I was asked to and I repeatedly said in the early years of my membership I did not like nor understand the platform. What is particularly worrying to my particular personality is that Facebook does not delete what I consider to be old rubbish/garbage I no longer need. This is the type of person I am, in my daily life I always have a regular clear out of clutter, but Facebook seems to enjoy infuriating me with constant reminders of what I said years ago, that is history as far as I am concerned.
I do not want nor need to share memories with the world, I can quite easily share memories with my friends in the real world when I want to. My Facebook account is virtually dead I do not login any longer and Facebook in any case is so outdated now.
And can someone kindly tell Facebook I don't need to be told every 15 Mins despite turning off notifications a thousand times. That I have missed so much in the last half hour. It's only people adding a new selfie or something else equally mundane.
It was learnathome.ru And after that was bbclearningenglish.com and engvid.com
I know my English is not perfect yet, but as my friend says I have a solid base.
