That's a pipe dream... And be careful what you wish for.
In what way? On both accounts. The individual propaganda outlets are bad enough, but their vitriol and ability to suppress dissent come from the social media platforms. Cut those down and the hypercharged vitriol and suppression begins to weaken. How to cut them down? Start by removing all protection from liability for libel and copyright protection, period. Their so-called "fact checkers" will then be put to the task of weeding out libel and copyright violations, rather than suppressing political dissent. That will cause them to shrink, and will begin to open the market to alternative providers, particularly if the benefits of the current protections only apply to organizations that have gross revenues of $1 million or less.
Next, get sensible with anti-trust enforcement again. Alphabet (i.e., Google), Facebook, and Amazon would have been sliced and diced back down to size in the 1980s and 1990s, and that should be the norm again.
one man on the corner with a soapbox is an annoyance, give that man a megaphone, and he becomes truly irritating to those on the block, but give him a Wall of Sound (metaphorically) and he will overburden the entire city.
No more metaphoric walls of sound for social media.
