Consumers don't care if their bread is made from Calingiri or Ytipi.
But consumers DO care if their food is made from GMOs, so just put a label on it.
Outside of GMOs, what do you normally think of companies that make decisions for consumers? Maybe Samsung doesn't think you need to know what kind of processor is in your cell phone, because well, it's pretty much the same, and you probably won't notice the difference. How about if a company that sells socks doesn't think you need to know if the socks you buy are really 100% cotton or a 60-40 blend of cotton and polyester? What if the company doesn't think you need to know if the socks in the package or green or brown?
Remember, it's consumers who are paying the bills. They're the ones paying for the GMOs, and for all the research and for the marketing and press releases like the one in the article and for the high-paid lobbyists that are working to thwart their preferences. In most things, the person who's paying the bills gets to decide. The fact that you don't think consumers need to know something doesn't mean you get to decide whether they get to know something.
