Never have I seen so much greed, virtual signaling, pettiness, and deceit.
Yes, greed and selfishness. This can probably mainly traced back to the bad marketing of Steemit. "Come and earn money,". This attracted mostly the selfish and greedy users. And the Hive blockchain is a hardfork of the Steem blockchain, and because of this most Hive users are is (or was previously) Steem users, so this cycle just continued.
By the way, I am also a Steem user. I registered on the Steem blockchain on 2017.05.17. A little bit more than 4 years ago.
