Now that the evil Mondelez (formerly Kraft Foods) owns them, it's open season on the not so nice things that modern business gets up to. However given that palm oil is used in everything it's a little cheap of The Independent to try and manufacture outrage against what was a beloved, British institution.
Just avoid products with palm oil, though that's getting rather hard to do. Don't bother wasting your time with this kind of junk-food journalism.
