The bad thing about that model is that it leaves the door open for ONO to delete your content if they don't like it

The content will not be deleted, Super Partners will have the rights to hide the content. No one can delete the data in ONO just like Steemit. And it's not about liking or disliking, content that would be against their common value would be hidden so that people can't manipulate the system just like people have been doing on Steemit, 7.02% of total rewards were taken by the top 20 authors in April, 2018 :)

And yes, let's suppose if being a Super Partner, I hide your content, you will have full rights to call for a referendum and let the community decide if the SP action was fair or not. Do we have this kind of system on Steemit? Decentralization doesn't mean that you do everything you want even if it's harmful for the people/society and this is what we are lacking on Steemit! People creating more and more bid bots and ripping people off.

In short, it's not centralized, rather decentralized with some proper rules/policies that will be implemented as soon as the international version is launched. On Steemit, it's now a bid bot game and trending page is the perfect example how a low quality content is advertised using money. ONO will have no bot, it would be for humans, controlled by humans :)

And yes, BTW, have you ever checked @berniesanders author rewards? :)

I would suggest you to go through the White Paper and check how the system will work.
