In this case it's you saying that the % i am giving you is worthless. If you feel that it is worthless, then why are you even bothered?
Aha! Now we're getting somewhere!
Because the PTS/AGS social contract has the potential to be a very powerful force and by taking extreme stances like this I am nurturing it.
You say, "I will not choose to participate in this agreement, because I do not need your end of the agreement". That is perfectly acceptable, especially given the support you have that you alluded to. You do not need my support, you do not need good vibes among PTS holders, you do not need to be part of the PTS/AGS family. Awesome! Sounds like you guys are gonna do just fine then.
