It seems disingenuous to say 'it is just a factual term, so meh, why is everyone getting so sensitive....etc'
I think everyone who gets involved in these discussions on breast/bottlefeeding know what an emotional subject it is, and that there are a lot of women who wanted to breastfeed, tried hard, failed and feel very sad about that.
I don't think this means that we should bury info about negative effects of formula, or stop trying to encourage b'feeding, but i do think a degree of sensitivity should be used.
Also when i switched to formula, I wanted the experience to be as close to b'feeding as i possibly could, going skin to skin, snuggling up in bed, I think it is important that if you do end up formula feeding that it is done with love, not with negative feelings in your heart (sorry if that sounds a bit odd!)
I think calling it artificial feeding just sounds cold and negative, like something that you would do with a doll.
I know I said it before, but there are lots of medical terms that one wouldn't use in day to day terms, because although they are factual and correct, they also lack sensitivity eg miscarriage/spontaneous abortion.
