Summary: written with AI from the case record.

What it's about
The Court dismissed (ended) their request for Supreme Court review under Rule 46 without deciding that question.
The dispute concerns Section 230(c)(1), which limits when an online service can be treated as the publisher of content provided by someone else.
Question presented
Whether the prohibition in Section 230(c)(1) of the Communications Decency Act on “treat[ing]” an online service provider “as the publisher or speaker of any information provided by another information content provider” bars claims that would impose liability for editorial decisions about how to publish third-party content.
