I didn't say NXT had a negative start. I said the only partially released source had a negative effect. So what I'm actually saying is that the NXT start could have been even better imho. With the at least partialy closed source it had kind of a bitter aftertaste.
There is no evidence this is true. This is pure speculation. If there were clones of Nxt back in November just after IPO ended, I would say Nxt would not be where it is to today. It would be way down.
