The paper boy isnt knowingly distributing, say, child porn magazine. If he were, the. he'd be an accessory. Big Tech does knowingly transport illegal things.
If the paper that the paper boy distributing has the occasional libel, then the paper boy is not liable because he cannot have a criminal state of mind for something he doesn't know is in contained within his cargo.
Finally, the paper boy is a boy, that is a child. Depending on the age he is not criminally liable no matter what he's carrying. Big Tech are not "niños de pecho", suckling bebes. They are large corporate monopolies with immense power, money, political influence and top lawyers
Finally, my solution is to de-centralize everything.
Since when have paper boys been held liable for what's in the newspapers? Social media is distributing someone else's opinions.
