If you dig through most of the vitriol online, the level-headed disappointment basically is:

- A yellow maw was advertised in the crowd-funded preview images, that's what people were expecting for their money.
- All updates along the way showing various steps mean nothing from a final colour POV (the last update from recent weeks could be an exception) because it shows prototype/unpainted/unmatched parts, so the assumption holds the colours will be as expected come release.
- Final product deviates in this regard, and it is a significant deviation/alteration due to its prominence. Most significantly, given its prominence for the planet mode look, the fact that its change wasn't alluded to in any way is what cuts deep for most


There was likely some combination of changes made to the design and the covid affected working climate (and soaring postage, especially for that behemoth) that meant that choices were made to either save some money in implementation (molds or paint apps) and/or not delay the release from early 2021 as planned.
