A major problem is that most major social networks take following (both in people and amount) in a kind of neoliberal way. More like a product to consume then people (which is where the problem of follow policing came from, demanding more "ethical consumption").
Also the "big 3" social networks of the past were a major facilitator in a generation gap in queer and trans spaces because of this sort of "somebody is always watching you" mentality. A cultural shift from prioritizing liberation to prioritizing safety (both are good things), and this idea of using social networks as a kind of panopticon of what and "who" you consume became associated with said safety; so much so that the things (and "people") you consume was deemed to be the most important part of your identity.
Also as another commenter said, this goes all the way back to accidentally leading terms on the old Livejournal days where followers were called "friends" and that lead to a lot of painful misunderstandings. So much so people had to clarify things about how they see their "friends" list on their profiles.
For roughly 20 years things accidentally and later deliberately got to the point where the validity of ones bond with another was seen as a manifestation of whether or not one can access their social media content, and how much of it. So much so that influencer culture promotes this deliberately as a form of marketing.
Anyway, it's good to see that trend reversing somewhat.
(Sorry for the infodump, this sort of thing is a special interest of ours).
