Nah, I think people who want GDKP banned are people who realize the obvious truth of GDKP - which Blizzard has already admitted to:

The important question is: ‘which makes Blizzard more money?’. Because Blizzard does not care at all about the amount of RMT, bots, etc. if it does not harm their revenue. However, If Blizzard finds that they are making more money through retained subs by keeping RMT out of raiding, then they will continue to enforce that policy.
