With all due respect why do you even care? These are best softwares out there and pretty much everyone is using them.
If you don't want to pay a fee maybe try and compile one yourself.
Because it helps me to calculate my daily profits and see if there's something wrong.
Besides, if there are hidden fees, then that's wrong and that's when I start to care.
There are no fees for any version of ccminer that I'm aware of. There are a few private versions of ccminer that you have to pay the developer for. A well known developer of these around here is sp_mod.
Thanks!
