OP is pretending falsely to help people "master Vim" via repetition. I'm using the same strategy to steer people toward better ways to learn Vim, without the lies. OP doesn't need help, it's the potential victims of that scam that do.
Again, I'm not gonna defend the opinion because I disagree with it, but johncoltrane can give his feedback as many times he wants to, and I think his feedback can suggest to change approach to the problem, not only to give up. He didn't said OP should just give up, so don't put words into someone else's mouth.
Plus I think it's great that he's suggesting to all readers free alternative for learning.
johncoltrane gave the same feedback last time, so I don't see how this is supposed to be helpful to OP. [0]
