You can craft features which promote a behavior or inhibit it.

To add to your point, let’s not forget that a certain social media site used their algorithm to boost content that angers people because it also boosts engagement. It shouldn’t be controversial to want a social media that, like, doesn’t exploit negative behaviors to generate more dollars, and I think your working towards something that specifically doesn’t do that is admirable.

This argument that a social media platform not doing evil things also exclusively means it cannot attract an audience in some other way is a false dichotomy.
