I think primeGPU made a wrong business decision to offer this miner in exchange for XPM when it came out.
We still believe it was the right one.
He had the fastest miner in the beginning, it made sense to solo mine at the time. But a lot of people who had the right hardware, didn't have 65 or 35 XPM, so they used Claymore's miner instead.
You messed this up quite a bit.
We had not the fastest miner but the only miner at the beginning.
(We still have the fastest miner at least for 280x).
Then Claymore's miner became better, difficulty became greater, giving everybody little reason to switch and go solo. There should have been a 10% dev fee from the start, instead of 65-35-25XPM per license. PrimeGPU would have way more XPM now and so would the users of his miner.
If you read the first pages of the thread you will see our reasonings:
1) We wanted to make money both for ourselves and our customers - hense the whole 1440 licenses/first month thing.
Note: everone who bought the license for 65 xpm either got a 30 xpm refund or an additional free license.
2) We were first and everyone was under impression it's another "xpm gpu" scam - so we made open-source-client / closed-source-server to make everyone a bit more relaxed about installing our miner. The dev fee just doesn't belong in this scheme. Claymore didn't have to convince anyone it's possible to have an xpm gpu miner.
