It's also the fact that bunny chests are a completely free source of income, as map farming requires them to have a bot constantly buying out maps in a price range going from 30-50K on average, which means if they don't get a portal, they're scarcely profiting or even losing money.

The only "positive" if you can call it that is that there's a limited number of bunnies that can spawn from each FATE which places a hard cap on how much they can be getting from this farming method and since it's potentially depriving actual players of bunnies it's liable to get much more backlash then they would from maps.
