Information overload is very real, and people are very prone to making mistakes when digesting information from social media.
The answer isn't to kill social media or force users to solve CAPTCHAS before posting. It's to improve those critical rationality skills and the ability to analyze information.
Social media algorithms are harmful, but they're ultimately dumb likelihood solutions that do naive grouping - it just turns out that more partisan/outrageous content tends to be more exciting and elicit more key value actions.
The fix isn't to try and play legal games with social media providers, but to teach users how the mousetrap works and what are the levers they can control (and the ones they can't).
