"Steemit users can upload anything they want, whether it be phrases, quotes, anecdotes, photos, videos, memes, songs..."

Apparently it's not the case, so why don't the managers of Steemit make up your mind first before you accuse others of wrongdoing?

If people are being censored here more than they do at Facebook, how is this website going to grow? For money? Hell no. The fact is, vast majority of people can't make any meaningful amount of money here at Steemit, or they simply don't care about making money (such as me)!
