I remember I read an article before how DA did a lot of features that were taken later by other social media like facebook, etc., even the platform owner -named spied if I remember correctly- was very humble and nice person, one time they made a feature for paid users and I made a sarcastic joke how this is not fair, he promised to bring it to free users and did deliver. I think DA failed unfortunately because they are not greedy nor evil like how other platforms are, and they are focused on a niche audience like artists, and artists are mostly broke.
