YANBU OP.
I remember visiting France many years ago and tasting Nutella for the first time. Can't eat it now.
On chocolate, Cadbury's messed about with for years, now inedible. Agree about Chocolate Orange.
I've even noticed that a lot of the traditionally better quality, high end chocolate is full of shit ingredients now. I don't like dark chocolate and I have struggled to find a decent milk chocolate bar that's not crappy.
