That doesn't explain a lot of the restructuring.
I mean Fae -> Numina? The fuck's a "numina"? Is that really the best name he could've picked?
More people further down go into more detail (and I have forgotten most of it so some of what I say here is probably wrong), but I believe there's a resort now, the order you meet the characters changed, everybody knows about the fae now so they're no longer in hiding, the game's on an island (?), and all sorts of other shit are all just weird and unnecessary changes.
Also blaming Itch, Substar, and Patreon isn't 100% correct. You should blame the payment processors/card companies, Collective Shout, and PayPal too.
NOBODY should decide what you spend money on (unless it's quite literally illegal shit that you're trying to buy).
