The WHO is declaring it a possible carcinogen. https://www.reuters.com/business/healthcare-pharmaceuticals/whos-cancer-research-agency-say-aspartame-sweetener-possible-carcinogen-sources-2023-06-29/
Edit: also, telling someone they should feel bad and stupid (along with the other language you used) is a bit rough for a discussion on artificial sweeteners. Especially as OP cited the source, made it clear they had no direct knowledge of the situation, and--it turns out--a major health body has cited potential dangers.
This is a good opportunity for us to be a little more civil.
I love the discussion here as to possible reasons why the labeling is different.
That said, there's a very good chance it's just because the initial version had 3, got translated, then someone added a 4th item and it never got translated.
