That doesn't make her actions not predatory, though.
She does acknowledge that it's fucked, yeah, but at no point does she ever stop doing it. She lacks a moral compass in this regard.
It sucks, too, because her Confidant has such an easy fix. They could've just made her a fellow part-timer at one of your jobs. That way, she's still working herself to the bone, but she's not taking your money or doing any of her other awful crap. The maid thing is pretty much just to be fetishistic, when it really didn't have to be.
She explicitly mentions working on several part time jobs on top of her maid job, making it extra clear that
she's being extorted for an exorbitant amount of money.
But it's nowhere near a Kamoshida situation, because her relationship with Joker operates on a mutual "give and take" relationship with trust as a key element. And the narrative that the entire set up is fetishtic garbage is so goddamn disingenuous. It's a seemingly goofy Confidant that becomes intriguing and depressing as you progress. It's not shallow trite like the nurse social link from Persona 4. Yes, there are aspects that are absolutely wink-wink, nudge-nudge, but I never felt I was being hardcore pandered to within confidant itself, and it doesn't preclude it from being good. In fact, i'd even go as far as to say that it's one of the best confidants, with a memorable hook, good twists, the right amount of sadness and an ending that is legitimately touching.
The biggest issue is that the romantic route completely sells out the character.
