I don't think that is something related with flaws, this man has its own idea of how new social media should be, is probably very similar to Hive and if it isn't should be easy for him to make a HF and start working in his own HIVE based blockchain to accomodate it to his tastes and will.
The issue is that he is too proud of himself to recognize that you've pointed out something interesting that he ignores. He is a genius so "who the fuck are you to tell me what I should do".
