Vote equality leads to the kind of astroturfing methods you see on literally every other social media site where it only takes an organization a couple of upvotes to get the ball rolling on posts, it is not always a guarantee but it gives it the momentum to have a chance at landing on the front page. You just post up a post or two a day or vote on things that mention your product and eventually something goes viral. It is usually too obvious when something is voted by a massive amount of bot votes because the actual activity in the thread is too sparse compared to the voted numbers, and if people don't like the copy-pasta your paid workers are putting in the thread as responses then that also damages your brand.

Wait, what were we talking about?

Oh yeah, no sane company would spend money on steemit when they have an end-product or service to sell and could reach 1000x the amount of eyeballs for cheaper.
