There has always been some of this. People that make a lot doing this eventually usually get called out. This happens a lot of places. There likely will always be some of this. There is a lot of great content that ends up on steemit too. That of course is my opinion, and you are completely justified in having a different opinion.
EDIT: I REALLY started enjoying steemit when I posted for myself rather than worrying about how much my posts make.
