It's a potentially negative financial marker to the success of their business model of selling skins if their skins don't sell, I don't think there's any more sentiment to the statement beyond that
The comment I was replying to didn't say they weren't selling, just that they were unaffordable to many people, so I don't really know what you're referring to.
Maybe it's a negative to alienate your customers in this way, or maybe it works financially to make skins just out of reach and 'aspirational' for most gamers.
