I think mejority of the people complaining about hive are %100 in for the money and not for the fun or work of hive. Basically you right if only they can change their mind set and learn how hive works there would probally disregard other social media
My sister was very active on facebook, I introduce hive to her and when she puts in the work and effort to get to know hive better, she focused all her energy and time on hive and abandoned facebook she calls it a waste of time
