On these platforms, their users have to compete against a well funded media campaign of celebrities, media orgs, etc... even for their own family and friends' attention. It is a really absurd level of engagement.
edit: The way American tech companies have approached the social evolution and communication via internet is centered around their propaganda influence and reach. In every respect, they have insinuated themselves into the communicative aspects of the "users" by introducing subversive practices, manipulation, surveillance and the continued active threat of loss of privacy to very adversarial actors.
It's just completely absurd.
