meh; i guess; it was tacky move to not put in readme and make it clear about donation. Technically i agree if he wrote the pool software a bit of donation is not awful thing; just a HUGE miss on not being extremely clear about it.
But the center ideal of "hiding" in opensource code is a bit absurd and it told your miner on output... Not like it was hidden at all in source; very clear. People and their drama was a bit real though.
First thing i do is grep code for donation lines; more of pool owners just downloading and running software without even looking at code. I am a bit concerned about irresponsible pool owners not even checking before putting a pool up...
