I would be happy if congress passed a law saying a social media has no liability for anything their users post as long as the algorithm is completely open source. If we had social media like that, they'd even have APIs that let users design their own algorithm and we'd see a golden age of social media emerge from it. Twitter seems to moving in this direction but they enjoy no legal protections from being open at the moment. Blusky is already this way I believe, but without a neutral and trusted centralized control it's a bit different of an animal.
