Well that's just a separate issue and not covered by this supreme court case. Section 230 of the CDCA provides a lot of protections to hosts and depending on the wording of the ruling, a lot could change in a lot of places. Youtube receives lifetimes of videos every day. If every single one needed a full screening before hosting, something would have to give. Costs would increase on their end. While I can say "they can just shrug off the cost" we know that's not how it would play out. Not saying I like it, and I think hosts need some responsibility, but these things are all tied together. Not to mention possible effects on ad revenue due to slower publishing of content and the likes.

Legal Eagle did a good video about it last week. I'd recommend checking it out.
