>Every platform that lets people submit content would have to stop doing that, because it’s an impossible liability to manage.

This is a huge assumption that is offered constantly, and always, without any evidence at all.

"letters to the editor" curated by employees would become a part of their business model and regular contributions would go away? Why would that assumption be incorrect? I wouldn't run a website where a casual user having a moment could result in my imprisonment. I would only allow non-lbtq content that didn't mention race or immigration, as the chilling effect there is real. A DA would for sure come after me if my site became influential.
