I think the split comes now that companies, such as FB, have focused to maximize 'engagement' with zero thought on the repercussions. Cigarette companies knew people were addicted to nicotine, but I guarantee in their planning sessions they talked about engagement or some other corporate fluff word.

It's less about having a good product or making a worse product, and more about the moral and ethical responsibility to consider what that addicting product's end result will be.
