I don't disagree. you are right, but this is a larger can of worms then just arguing against Cortese. It's a trend, that while leaving a dodgy taste will provide the club with more funds.
This is an ethic used by many other organisations. So may not directly contradict the idea of 'business ethics.'
You are trying to launch a crusade beyond this club, into the wider capitalist world. Either go for it or shut the hell up, your whinning is getting annoying, we understand your dislike for it, ok. (I understand this has been campaigned against before and upheld..... you really will need some luck.)
