That's the trouble with words like 'artificial' and 'natural'. They mean nothing. It would be better to call them refined additives, because I expect the "stevia" would be in a refined, extracted form when added - whether substantially changed from the form present in the plant or not, this could be considered artificial, if we insist on using this word.
The point is less about whether Mangione himself killed the CEO than schadenfreude at a protected class who keep thinking they're better than the rest of us. I realise all sorts of other speculative discussions are going on about whom to point the finger at, but it's more interesting to consider the implications of taking back power from the greedy and priveleged by force (especially when we're cowed into thinking we're powerless).
