Has changed already in the past Node earnings split changed to 35/65 from 25/75
But this is not the main issue. The problem is that it makes economically now because of the high price for PRV no sense anymore to fund your node. Instead, people will shift over to a funded stake. And in this case most of the earnings will always go in one wallet of a third party. This leads to having them one day so many PRV that they will be able to control the network. So no decentralization. No one claims that they will act evil intentionally but hey blockchain ist about a trustless setup. If I have to trust a third party to not jeopardize the network then the fact it is a blockchain becomes nonsense. I can also decide then to trust a bank or another third party. No blockchain is needed in this case.
