Awesomeminer and HiveFarm violate the cgminer license since.
They have firmware that runs with their software that violates the license.
I've no idea about the other two.
Bro you are that guy? tbh so annoying. I noticed this message on other threads. Learn to debug their firmware and find out for yourself if they are doing anything bad and stfu. your messages don't help anything or anyone.
They violate [n]my[/b] license.
Of course I point that out.
