I am usually paid for what I develop and open-source...
And after you open source it, somebody works for free and optimize your work and get a few beers in donations. I don't understand your problem.. Miners needs the software to be up do date to earn money. Old kernals are not profitable any more.
I have no problem with you optimizing my work,
as long as an actual optimization takes place which hasn't always been the case lately (I tested what you did on lyra2rev2 side algorithms (blake,bmw,cubehash) and I found absolutely no difference while the numbers you reported were by itself equivalent to half what you would get if you had removed these algos (minus cubehash...), which from my stand point is more or less equivalent as saying that what I release isn't optimized. So at least make sure it is true before saying it... (especially when you say it almost every days... hey I understand that you need to motivate donators, but please don't do it repeatedly on my back
)
ps: I don't deny that you did a good job with quark and x11
