Apparently someone shared my article about ethical anti-design on Hacker News and I saw a number of people talking about how the name carries some negative connotations, and that something like pro-social or humane design would be better

Honestly, yeah

I like the name ethical anti-design because it's eye-catchingly ironic and it really specifically describes what you're doing--that is, putting more friction around traditionally addictive behaviors. Pro-human design is a more positive way of framing it. It also sounds like it could be an umbrella term for a bunch of ethical design practices, one of which might be ethical anti-design.
