To quote Andrew Lewis, "If you are not paying for it, you're not the customer; you're the product."
You'll know when a user of a Dopamine-backed app installs Space, and that's useful to you. Measuring people trying to give up an addiction feeds back in to understanding the causes of addiction, and in your case presumably gives you quantifiable information you can use to make Dopamine more effective. Saying you made it and give it away out of the goodness of your heart seems a little underhanded.
Your company is still about making shit addictive. Its customers will inevitably be those with the money & inclination to make their app addictive - social media & mobile games. Its morally pretty close to adding sugar to junk food or selling cigarettes.
You were going to clear up "mob misconceptions" about ethics but it turns out you had nothing to say, just an "invitation for discourse".. while most of the tech world has been in on this particular discourse for years, with constant media coverage, and we know its a problem.
But I'm pretty sure you know all of that. Don't expect public approval for making glorified/AI-powered slot machines, they're still just slot machines.
Bruh. Just adding another app to 'counteract' the effects isn't going to suddenly clear you of ethical issues. It's the equivalent of mcdonalds selling salads...
