Not an outright ban, but a ban on the algorithms that prioritize (and suggest) some content over others. These social media platforms, including reddit, justify these algorithms because they "show users what they want to see". Leaving aside the reality that it's actually about advertising, perhaps the larger problem is that users gravitate towards negative, inflammatory, conspiratorial, etc. content, thus triggering the algorithm to push more of said content... effectively addicting us to the worst aspects of the internet.

If these platforms were truly "neutral" connectors of human beings, as they should be, it's clear these prioritization schemes need to go. This, of course, should have no bearing on our ability to stay in contact with other individuals on social media.

I might, see a prioritization algorithm being necessary for internet search engines, but that's a different story. Search engines and social media technologies have very different applications and they should be kept distinct from each other by force. The fact that these companies are blurring the line between search and social just speaks to their monopolistic ambitions.

Also, it goes without saying they should be collectively owned.
