I share Hive account@baah's point of view. When you raise funds from the community in promise for something, then it's up to you to make sure that you're actually able to deliver and not just hope that you can figure it out.

Removal of inappropriately used assets etc from their assets (site/game/discord/etc) I don't see as a means of hiding their behavior

You probably miss some context. They removed the content from their homepage saying how many packs they sold (7500 x $ 10) so that they could tell the artists that they didn't sell much at all. That's what they stated in the comments, saying that they actually dropped most of them for free (although the landing page said "sold").

plenty of opportunities to run away with the money

For sure there is mismanagement of funds. Lots of funds withdrawn to exchanges (it's all on chain).
Building a game is expensive but something seems off.
Plus hearing some of their customers not getting refunded for undelivered work and unpaid devs that quit, just adds to the mix.

some method of tracking royalties etc for those artists

I hope they'll do it but I don't see it happening. I suspect that they'll screw them over with nice words and give them nothing.
They are broke. Justin has debts and can barely pay rent.
