Does it matter if it's something new or not?
If it is better and IF it is actually used for the PS5 it could be a positive.

Yes. Especially if individuals are proclaiming it as some kind of "special sauce" and a feature "never before seen" in the tech industry in order to hype up their products under a false narrative. - It's disingenuous.

Sadly it happens regardless of platform holder you support.

Is the cooling method better? Potentially. But the question remains... At what cost? Could it have been done cheaper? Better perhaps?
