Indeed. I can't empathise with the OP at all. I guess it depends how you use these platforms. For them, it seems to boil down to:

I’ll still come across the best content organically - such as a friend sending me a video or a tweet, or when I go searching for that content with intent.

This person is very lucky to have such interesting friends whose interests align so closely with theirs, and who are willing to put in all the effort of content discovery on their behalf. My friends mainly send me dog videos and memes.
