I think here position was quite clear and to be fair to her, it wasn't the first time she expressed her frustrations with the platform. She did so even when the price was relatively high and she was earning quite a fair bit on her posts.
Her point is that the place has changed from the original dream of content creators being able to get rewarded by simply working hard on their posts. Sweat equity if you may.
The distribution of stake is more even now than it has ever been. There are apps that have large stakes that give out significant upvotes to content creators on them. Back in the day, there were a small number of premined accounts, massive inflation, whales upvoting each other and a few people being fortunate enough to being upvoted by a whale.
There still are people who have earned sizable stake through sheer effort. @tarazkp is a living example of someone who has done just that.
Today, it's all about the bid bots and how much you can pay for promotion.
Bid bots are all about the largest stakeholders (and delegating investors) having found a way to take a larger cut like they used to before delegations (and bid bots) existed and when they circle jerked. But so what? Most of the apps have their own coins based on their own business models they are free to distribute as they see fit. Steemit Inc fell asleep at the wheel and SMTs got delayed. Fortunately, we already have them on a side chain and Steemit Inc is now ready to implement them, too. Curation will be done to distribute dozens or hundreds of coins in parallel. The market will sort out that ecosystem. Be it done with Oracles or whatnot.
Basically the dollar value on a post does not reflect the "quality" of the post. (Quality is subjective, but it's all within reason).
I think that's irrelevant. The only thing bid bots do is enable stakeholders to make money passively instead of having to curate. Yeah, content curation with SP does not work very well. It never has and bid bots have little to do with it. Back in the day, it used to be the same small group circle jerking. Bid bots are vastly better because they can be part of an economy where money buys attention. That idea is the very foundation of why STEEM is capable of having any monetary value at all.
The impression I got was that she feels too few people have all the power here, and most of them are not really interested in the old dream. Which is a fair assessment I think.
Why quit now of all times and not a year ago? I think it boils down to the price of STEEM and not being able to live off STEEM.
This platform is rapidly transforming into something other than a mere blogging platform where SP based curation is used to allow the most eye-catching content to rise to the top. There are many apps now for a variety of purposes including gaming and gambling. All those apps have stake and they're using it to reward their own users.
Despite the price tanking Steem is still a total paradise for content creators. The typical post earning one USD worth of coins now wouldn't earn a single cent out there in the real world.
The only way is up. Steem Power will be a valuable resource in the coming years. App developers are getting the message that Steem is actually a pretty good platform for creating DApps because it's fast, free, scalable and because it has a community of users enthusiastically trying out any new app launched on the platform.
