I think it would be best to both parties and to all miners if this would just be for free. Without the dev fees.
Please remove the dev fees in your zcash miner @Claymore. Just let it be for the public and all of us miners will appreciate you more and I think @mrb would have no objection to that.
Please remove the dev fees. Just this once.
Thank you.

?!??!??!?
There is no logic in what you want !!
By going to the store if you donate bread or have to buy it?
Developers also need to eat!

I understand where you are coming from but there is already animosity in the air. If the miner released by @claymore is open-sourced there would be no drama. As you know the issue is, the source of the code is open and created by another good developer, used by claymore as admitted by himself, enforced small % as dev fees without acknowledgement of the source. This is just one way to settle the infringement and there can be many others.
To answer your store question: Find money to buy food to eat, but have it the right way. There can be ways other than enforcing dev fee on this one.
