That's why I proposed the paradox. At what tipping point does the arranger become the speaker?
Read 230.
https://www.law.cornell.edu/uscode/text/47/230
"No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."
"No provider or user of an interactive computer service shall be held liable on account of any action voluntarily taken in good faith to restrict access to or availability of material that the provider or user considers to be obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected.
230 says you can moderate however you like and what you choose to leave up doesnt become your own speech through endorsement osmosis.
I agree with 230 to a point, but at some extreme it can be used to misrepresent speech as "someone elses." Similar to how the authors of newspapers wouldnt be the speaker of a ransom note because they contributed one letter or word, and it woild be absurd to claim otherwise.
If the arranger is the speaker, restrictions on free speech apply to their newly created context. Accountability applies.
