I think the element of it that I don't particularly like is how they frame themselves as people who value their time and mental health because they carry around a second, intentionally limited device. They kind of play this "social media is really bad, phones are really addictive" angle but then they don't actually give up on any of that stuff because they still have their extremely expensive high-end folding phone on them at all times as well. It all feels so performative to me, like they're not actually willing to make sacrifices themselves but still want the social cred/respect from pretending to be aware of the problem and part of the solution. But they're not, really, because they're entertaining this fantasy where phone addicts can magically get their lives back without changing their relationship with phones. If anything, they are contributing to the problem by encouraging people to buy and use even more devices.

I much prefer the anti-addiction/"minimal" phones that are either a) very small or b) have an e-ink screen, but are still marketed as an actual phone (not a "secondary" device). Those manufacturers intentionally put up walls to frustrate and force the owner to change their habits and re-wire their brain, rather than pushing this fake "you can have your cake and eat it too" philosophy to combating addiction.
