Sure I can explain the points in more detail. Sorry for the misunderstanding, I'm old and when I see acronyms I get flashbacks.
Oh, I'm not actually a 'good' artist but there is a chance you seen some of my work around F95Zone and a few other sites. I've helped clean up some translation projects (Title Screens, Menu Command, other small assets), I've cobbled together some sprite assets for
The Last Sovereign using other resources though Sierra Lee credited me under a different name (if you liked Simon & Robin's hug scene that was me, I'm also responsible for Patty, and pretty much at lot of the iffy sprite art people complain about probably came from me), and I have been known to Photoshop a few things for the lols.
* While some would probably just like to be credited and get exposure others not so much.
Not all artist are in it just for the money but they do like being appreciated. It also hurts when they are called thieves by fans that think they stole their own creations. Building up a reputation is also important if they hope to go big someday.
* A few of the assets were meant to be exclusives for their respective games.
This was to point out just because art is out there doesn't mean the original artist may have the rights for it. Some sell their work under exclusivity deals which was the case with Chloe's Original design. While fan art was released it was meant to promote Future Fragments, not be repurposed by another developer for another game without their permission. A distinction between fans and business owners.
* Some are fan art of other much bigger IP which if they get wind of things might be more tenacious then an artist just saying don't steal my stuff or I'll tell mommy Patreon.
A point that this could have went a lot worse for Arc. But this is somewhat of a some up of the situation so I can understand it being taken out of context. Why Arc made the change was to protect his financial interest. Why an Artist complained to Arc was to protect theirs. Why was the joke "I'll tell mommy Patreon" used? Lawyers can be expensive but anyone can report a Patreon creator for misconduct which could get their page shut down for review or possibly suspended.

Just because Artist protect their work doesn't mean they don't have passion or dislike that people actually appreciate their art. It's one of those it's just the nature of the beast in the industry and it gets more cutthroat when business people are involved. Hard to say how much money was spent on Chloe's design or how much Arc profited from using it. Whether the fans like it or not since Arc didn't give credits to these other artist is just feels like bad form so some will feel offended.
