Dumb WWYD? re: oatmeal

Dreamsicle23

I bought some Quaker reduced sugar flavored oatmeal to give to DS.  He liked the baby oatmeal so I figured he'd like the grown up version.  I gave him some earlier and he was eating it, but making kind of a funny face.  I tried some and I was surprised that it was really sweet.  I scoured the ingredients list and I see sucralose!

I am pissed because nowhere on the front, top, or side of the package is there anything to imply in contains artificial sweetener.  I'm leery of things that say "sugar free", but "reduced sugar" usually just means less sugar.  Am I a nut job if I send them an angry email?  I usually check packaging, but who has time to read that tiny print ingredient list on every single item?
