You realize this is the exact opposite situation? How long until “conservatives” on FR argue that FR is obligated to unzot trolls because, uh, because.
Say I am writing a book, and when I put it down, somebody who disagrees with me picks my book up and starts writing in it. I will be justifiably upset as they are writing in my book.
But say I am supplying paper for people to write their own books. And I determine there are some people who I don't want to be able to write a book, so I refuse to sell them paper.
FR and even DU are spaces for those with similar thoughts to write their own book essentially.
YouTube and Twitter and such are the paper manufacturers.
When those that control the access to the modern version of the printing press exclude some people it is very different than when some people decide to write their own thing on paper.
Youtube is effectively a monopoly and it needs to be treated like a telephone company.
