Quite a few people that are NEM stakeholders are also part of the NXT community in more or less important ways. At first NEM looked like a clone that was going to feed of NXTs success like a parasite. Unfortunately not many took a closer look to see what it really is.
I think you can clearly see that 2Kewl hasn't taken much time to do research on NEM and therefore assumed it's just another clone.
It's the same with people that hate on Ripple saying how centralized and crappy it is. Some people just take the easy way out and hate everything new that they don't know.
