I find there's even negativity about Steem outside of Steem. the reasoning is not always clear, but a lot of times it's some kind of grudge against the platform itself. Like a day or two ago I was watching Decentralized TV on Youtube and he was talking about EOS, and not only did he not understand the concept of EOS or how it will work, but then he just says "and Steem Sucks" for no apparent reason. I can understand his reasoning based on Steem's less than stellar launch, but Steem is now further along than probably most other crypto projects in serving it's intended functionality. I think the term that suits the content produced by these FUD-Muffins the best is "pessimism porn."
