GP argument is similar to the common carrier argument. Some communication channels (e.g. post, telephone, and maybe YouTube) are so pervasive, important, without comparable alternatives, that they should be considered as common goods and regulated as public services, rather than private companies. In particular freedom of speech applies to their users.

I would be for the common carrier argument if the logical extension that YouTube also gains the protections afforded to common carriers. No more having big companies get special treatment in abusing the Content ID system.

As much as I dislike YouTube’s policies in general, I find it difficult to argue against their current actions simply because powerful entities are already abusing the system behind the scenes to moderate content themselves.

Yes the size most certainly matters, obviously Facebook should be held to a different standard than some niche social network for pet owners with 100 users. Monopolies should be held to a different standard.

I'd argue that the nature of the business should factor into it as well. Since Youtube advertises and presents itself as a platform where any user can upload any kind of content excluding pornography and dark stuff (eg. animal abuse), I don't think that censoring on the basis of political views alone is justified (I'm not familiar with David Icke, so I can't speak for this specific incident).

YouTube is pretty clear about their stance on what is and is not allowed. They have made it very clear, in particular, that coronavirus misinformation is not allowed. I see little difference between choosing to censor pornography and choosing to censor coronavirus misinformation. Both are protected speech in the USA but they are both also things that are allowed (and is reasonable to) censor if the platform wishes.
