For example: currently if someone doesn't want to see someone posting "objectionable" content - you have to identify them, then sue them. That's a problem if there's messages you don't like but you can't make illegal. But if instead you can sue the host, you can just keep suing the host, and the host eventually starts disallowing that content on its services, even if it is legal. Like they already do for adult content.
But the incoming administration has stated that content they believe should be illegal is anything that says LGBT people have the right to exist. You see this with their consistent bans on library books, their attempts to reclassify books as fiction if they can't block them on "harmful" content, etc.
We can see that this is nothing about ensuring an ability for people to hold corporations accountable to people, but specifically to enable censorship: because the proposed removals of protection from prosecution for content they host is the only place that proposed changes increase corporate liability. Every other proposed change removes the ability hold corporations accountable, removing worker protection, removing or hamstringing the agencies responsible for regulating safety, and removing or limiting the liability for any accidents, disasters, or dumping.
