You see people trying to use it that way, while wading through a morass of paid advertising and promoted memes. I can use a brick as a hammer, too, but that doesn't make the brick a hammer.
Why do so many people forget that they control their feed? Maybe less than some of us would like, but I carefully curate my feed and use mute and so on and my feed has very little junk in it. Mostly family stuff and jokes/memes, with some ads for stuff that actually does interest me. It's not hard. Most of us here solve harder problems every day.
