Twitter is very top heavy in regards to who posts and who gets followers / draws interest to the platform. You want Katy Perry & Co. owning Twitter? It wouldn't be an improvement, it would end in disaster. There's no scenario where you can distribute based on content creation and have it not end up like that, it'd be top heavy (relatively small group of outsized owners) in every outcome. When it comes to content, creators are a hyper minority in society (especially those that do it in a prolific manner), mimics and consumers are the extreme majority.
Ok, so make it not a pure worker-coop. I don't think a traditional cooperative structure would work on this anyway, even though expanding the "work" to people who not only reply but also retweet and like might get beyond the typically 1% / 1-9-99 rule of the internet[0].
Would I want only the "content creators" to make decisions on the platform? No. Right now, they don't even have that much official say, if any. I'd prefer that they have more say, that contributors have more say, and that lurkers have more say.
