I think it's because its main use in this particular context is to produce results that the creator does not have the skill to produce and/or does not want to invest the time to produce.

I guess you could argue that drum machines offered simplification/automation when they first appeared compared to the option of a human drummer, but also, those machines opened up all sorts of creative and stylistic possibilities that simply couldn't be done by sitting someone at a traditional drum kit. Using AI to make music doesn't do this -- it's a shortcut that has no argument in its favor whatsoever except that it saved the person making it time (and/or enabled them to generate something they couldn't have produced through their own work). That's why it is fundamentally uncool in a musical context, and always will be.
