You are right, but dislikes will help people to notice their mistakes and correct them, sometimes we think that something is good but actually it is not, in this situation we need people's opinion, if it is true then we can continue but if it is not we can stop it.You have a point, but dont you think it might have some negative results? Most people post on social media just to feel loved, hence they are usually very serious with the amount of likes they get. I have seen cases where people commit suicide due to few likes.
Commit suicide for having less likes is very strange for me
