As much as I agree with the sentiment of responsible companies (with my upvote), IMHO the reality is that consumers are the ones calling the shots.
Demand is like a vacuum suction. When there is a demand there will be supply, even if some don't choose to provide on moral grounds, others will fill in. No demand, no supply.

We have an obesity epidemic. More people in this country are overweight than not overweight. It's becoming a national health crisis, and costing us a lot of money. Type 2 diabetes, renal failure, and the like are preventable.
I think this article sums up my feelings on the whole situation. We have a health problem, and the cheapest, tastiest products make the problem worse. https://medium.com/health-the-future/918b3d08f21f
