What exactly prompted the hatred of her?

I don't get what other pop fans mean when they claim she's 'inauthentic'. She's not any more 'real' or 'fake' than every other current day young female pop star. They were all doing something else then pivoted to pop music. I think her music is fine and there's great potential there. You can say at minimum she's a breath of fresh air because she isn't a product of Jack Antonoff of Dan Nigro. Seems to me people are just unwilling to not have something handed to them by the two aforementioned hit makers. They already picked their 'team' and now everything else is the enemy. It seems really odd that of all the also-rans that have popped up in the last 5 years; she generates alot of vocal ire. The critics seem to like her quite a bit, but online 'music fans' tend to have a completely unfounded hatred for mere presence in the space.
