The idea isn’t repealing 230 - it’s to recognise any platform that’s manually curating content as a publisher. Then if that publisher hosts illegal content, they’re liable, because if they can curate some of the content, they should be responsible for all of it.

Also political feasibility in the USA isn’t the end-all be-all. YouTube certainly wants to do business in other countries/regions - such as the EU. Google is a public company, and as such it’s executives have a fiduciary responsibility to the shareholders. Right now, since other megacorps want Google to censor content so their ads don’t run alongside XYZ content that you don’t like, Google is following their fiduciary duties. But if a regulator steps in, it becomes a matter if “oh shit doing business in the EU is more important than doing business with cocacola”
