I said that recommendations themselves are materially differwnt from hosted content and therefore are not protected by section 230.
However, something worth noting: wherever 230 lands, there's not some regulator using discretion in enforcing it (like a prosecutor deciding when to charge someone with murder) -- this is a law that gives tech platforms a defense from the private lawsuits that could otherwise put them out of business (e.g., suits by indviduals/businesses for defamation because the algo ended up recommending a "John Smith is a lying fraud" video).
