What Lorde said was that the subject matter of a Gomez song portrayed women negatively.
"A song came out recently by a big pop star (Selena) and the lyrical thing is 'when you're ready come and get it, I'll be sitting right here just waiting' and I just find that so pathetic and I don't think girls should be listening to that kind of thing and I don't think that is normal or healthy."
This would not be out of place on NSG. Lorde also said that they considers herself a feminist (and, having asked a few girls a year or so older than her, it's not actually that common a self-description but the sample size is less than five).
Gomez disagrees and the tone of her reply is, essentially, the reason for the title.
"That's not feminism. [Lorde is] not supporting other women."
This is obviously referring to Lorde's remarks (which also apply to pop music more generally as well). Gomez says she possibly won't continue to cover Royals (Lorde's song, which, to my knowledge, is about the same issue that pop has as it exists for hip hop). Source.
That's the context of this discussion. The question to consider being: "Is Gomez correct? Is feminism about supporting women?"
Personally, I kind of agree but I disagree that Gomez's remarks apply in this case. Lorde is trying to support (other) women by identifying and seeking to change bad ideas/practices that negatively impact on women. This would, of course, be the sort of ideas that songs like Gomez's perpetuate (assuming Lorde is right in her interpretation... I've only ever heard snippets of it in ads*). Gomez is confusing, "I'm a woman and I should be supported by feminism" with "Feminism supports women". That is to say, Gomez is too close and, as a result, is being too narrow in focus.
*Although that's actually irrelevant, whether or not Lorde is right, I believe that she is actively doing what she thinks is best for women.
