How the platform and the vendor split that money is irrelevant to me, and I’m not convinced this would become cheaper - evidently consumers are willing to pay the current price, so why wouldn’t the vendor just increase their profit?
In the same vein: Games don’t cost less on the epic store despite their lower (compared to Steam) either, so as an end user it makes no difference where I buy games.
Maybe you like paying an extra 20%. That's your business. But fees like that affect the viability of lots of business ideas, including games. Having lower fees increases the pool of indie games.
