Websites and TV stations have the same first amendment protection. The main difference is that users do not contribute content to TV stations. That's what 230 protects.
Public access was very limited in bandwidth: one simply didn't have thousands of people posting content. As a result, public access was heavily curated and subject to the same broadcast restrictions as traditional television.
Even allowing that, public access isn't much of a thing anymore. In modern mainstream television stations, there is absolutely no user-generated content.
The fact that we've tolerated this for so long is appalling.
As soon as you start deciding to show some content and not other content based on the content of the communications you're making editorial decisions. Algorithms or not, it's a judgement call.
Without that they'd be subject to the same constraints as your average newspaper or TV station. Which is to say not a lot of constraints. But there would in fact be a means to address the consequences of their editorial decisions.
