Here’s the way I’m looking at it:

Ad-supported social media companies (ie all legacy social media) make money by showing ads. They control what you see, using algorithms, to make you more likely to keep scrolling and clicking etc.

Toxic posts are most effective at this, so those posts are boosted by the algorithm and the toxic content creators get rewarded for it.

With value for value zaps, content creators can be rewarded for posting better stuff, and without a centralized entity depending on ad revenue, there’s less incentive to implement the toxic algorithms.

I think the assumption that people will natural gravitate toward a toxic echo chamber is wrong — it’s only been that way as a result of the incentive structures, not human nature
