I think it has something to do with a focus on the outcome/s rather than the process. Steemit is essentially a market for 'ideas' similar to a trading market.

I can see many similarities with my development as a trader, at first I was entirely outcome motivated, what my p/l was on the day, the win/loss ratio. If I wasn't doing well I'd look to blame the market, telling myself the algos had an unfair advantage or it was being manipulated.

As I went through painful lesson after painful lesson I learned to accept the things I had no control over and just try to develop my process, refining it and improving inch by inch.

You can see the same refinements in some of the writers here, just focusing on their process and looking at where to add value. To an outsider it may seem incredibly unfair but as someone who has read and communicated with some of the top content creators I can see the process based mentality in full force.

Until you slip into that journey or find similarities in other areas of your life then it's much easier to just look at outcomes and negativity ensues.
