You should try to talk with The Doctor Tekcomm. He would show how it is spending 140h of coding just for pure pleasure sharing his work with others for free.
Greed is the root of all evil...
So this guy should just give away his hard earned time, knowledge and advantage? Sheesh.
Since there is no problem with Vega 64 to mine at 7Mh/s at stock and 7,4Mh/s on LC bios, there is no point to share with kerney666 at all. With stock bios on Windows miner I would be able to get only 6.75Mh/s with his 25% dev fee. Without any hesitation I would accept 15% (7.5Mh/s). And I bet there would be thousands willing to buy his product just to not to deal with Linux.
It is not a matter of "give away his hard earned time, knowledge and advantage". It is a matter of the market capacity. No one will pay for the thing, if he can have the same for free. That is why I offer no more than 15%.
Just because it is fair. 15% is much better than 0%.
