Reverse chronological + subscription (ie. the user must actively make a choice to follow some channel or creator to get them in their feed). This is how most platforms started, and while there were still issues (eg. rewarding frequent posting) they seemed a lot less problematic than what we have today.

The main issue isn't the misinformation or disinformation; it is how quickly you can amplify reach and reach millions. Reverse chronological + follows based on active user choice would largely address that issue.

People think that's what they want but they really don't. For most regular social media users if they haven't checked their feed recently they would rather see major life events (birth, death, marriage, graduation) prioritized first instead of a picture of someone's lunch.
