Earlier quoted context omitted.
Facebook was great in the early years. No ads, no political spam, no viral garbage, no pictures of what your friend ate for dinner, no psychologically manipulative algorithms. Just people talking to their friends and posting pictures of themselves hanging out. If someone made a new social network like that, I'd sign up today.
Excluding the "ads", how would you prevent users from posting "political spam", "viral garbage", and "pictures of what your friend ate for dinner"?
Facebook does the opposite now, which leads people to use it as a content consumption platform rather than a social network. Obviously that's what Facebook wants, since content consumption is infinitely more profitable than people posting on each other's walls all day.
