This interview with Senator Blumenthal about KOSA is interesting: https://slate.com/technology/2023/09/senator-blumenthal-kosa-kids-online-internet-safety-ai-regulation-congress.html
He claims KOSA won't stop kids from finding queer content if they want to find it, but will prevent "algorithms" from serving it to them against their wishes.
My guess? He doesn't understand algorithms.
