It isn't fair play, again and again there appears new great projects and algos, but only for nvidia, so what amd miner to do, to burn cards?! It isn't fair launch from the start, because it centralized by nvidia gpu's, like 90 % other coins and algos.
So about what decentralization we talk??
AMD GPUs have always (=last 10 years) been sub-par, but the fanboys refused to realize this because they thought a GPU that's great on ONE algo (eth) is a better choice than a GPU that's great on EVERYTHING EXCEPT THAT ONE algo.
So after making bad decisions, please, by my guest, to cry me a river.
