I like and read Ben's stuff regularly; he often frames "better" from the business side. He will use terms like "revealed preference" to claim users actually prefer bad product designs (e.g. most users use free ad-based platforms), but a lot of human behavior is impulsive, habitual, constrained, and irrational.
To an MBA type, addictive drugs are the best products. They reveal people's latent preferences for being desperately poor and dependent. They see a grandma pouring her life savings into a gambling app and think "How can I get in on this?"
I agree that is what he is doing, but I can also justify adding fentanyl to every drug sold in the world as "making it better" from a business perspective, because it is addictive. Anyone who ignores the moral or ethical angle on decisions, I cannot take seriously. It's like saying that Maximizing Shareholder Value is always the right thing to do. No, it isn't. So don't say stupid shit like that, be a human being and use your brain and capacity to look at things and analyze "is this good for human society?".
