Indeed, there are legal obligations and such but, perhaps, the problem is that not all people assume social platforms are neutral in the way they do other media outlets? Maybe because one can have extreme political views and easily find other like-minded people then one can become somewhat blinkered? If one's platform of choice is also stifling some content there is still enough of other stuff around that one may not notice?
