You may be thinking of the "CDA 230" nonsense that will not die, where people claim that companies can't moderate their customers because they'd be liable for what they post.
The opposite is true. CDA 230 makes it clear that companies can moderate their content without becoming responsible for it.
I've never heard anyone claim that companies can't moderate content without becoming responsible for it. I've heard people say that if publishers show themselves to be capable of censoring, then the legal protections should be rescinded and they should decide if they are a platform or a publisher.
