Does "make videos with lots of upvotes more visible" count as voluntary curation?

Even in the absence of that, hopefully you can see why they'd want to remove content as described in the points I listed above.

I'm not all the comfortable with all curation/moderation/censoring/etc being based on "government orders." That means that government will get more involved in this process, and corrupt governments will have more ability to control the narrative. Not sure you've thought this through.

It also is a very costly process currently for YouTube and facebook (etc). Do you want taxes to pay for that?
