>Then I think there's a core distinction between hosting content and as you put it "finding new content for them".
Yes of course those two things are different, but YouTube does both of them and both of them are necessary for meaningful participation in the public political debate.
>but recommendations/search fall under curation and curation is very much back in the realm of TV/newspapers where the proprieter exercises control.
When users search somewhere like YouTube or Google, or look at their recommendations, they are typically not expecting to get content ranked by how well it falls in line with the proprietor's political outlook. They're trying to get content that matches what they searched for, or in the case of recommendations looking for content the service thinks they might be interested in, not content that the proprietor thinks they should be seeing to further their own political goals. Search, and to an extent recommendations, fall under discovery. People don't go to YouTube or Google or Facebook or Twitter to see content curated by those companies. If they want curated content, they go to a specific channel or page or account, or to a website like the NYT.
>I think that does entitle them to shape the political conversation, although I could see some argument for a great deal of transparency in exactly what they're doing in that regard.
I'm curious if you would you say that if they were hiding content you agree with and promoting content you disagree with, or what you would say if there was an election coming up and they were hiding content in favor of your preferred candidate and pushing content in favor of the opponent.
