Even when it is only cosmetics, it creates a have's and have not's situation, it's a psychological assault on people who already paid for the game. It also has negative effects on the game's design, even if indirect and "minor"
That's because many who play the game sit in the old paradagim of gaming where games were complete, or sold complete with additional patches. This is a game that requires ongoing support as its an ongoing project in ongoing development. Micro-transactions to help support that process and momentum that is actually optional
I mean, it's just my opinion, I feel like supporting it will just make the gaming industry get worse and worse, and saying "It doesn't affect me" means you lost.
Evidently you disagree, no biggie, just wish more people didn't.
It's not getting worse, it's changing, and that requires different tactics. The model for Elite appears fair and considered; it creates some interesting customs for those with a few coins (rather than donate signs everywhere), that do not affect the balance in-game. I caveat this with work in the games industry and seeing the battles to keep everyone well paid and projects progressing.
As for the colour white, there's a mis-equating of an understanding of time spent on an item and an item's value to the consumer. By no means do the two have to equate. If I could magic a car into existence, as an industry, it would still carry an expected value. How it's built doesn't necessarily equate into what it's worth. It's why television celebs or sports people can ask so much money; their skill maybe no different to another actor, who would put in the same time and energy, but their market value determines the price. White, green, blue, they all carry market value, and its fairly cheap, after all. It's just a bit of fun tagged to a donation to keep the project going (and also to keep people engaged).
I'm tempted by the raider kit for Python, I've got one colour laser. No bothered with the trails. Each to their own, but there's more critical arguments on this sort of model than I'm seeing represented here.
