I have also said that if the fighting spirit is strong then the technical will come eventually. Lets look at a GM run. You need to beat GM's to get a norm. At that time GM's will probably be your technical superior. So you will need tons of courage.
Note: Competitor analysis and profiling can aid but it cannot replace courage.
So when I see someone who attacks a training program meant for the juniors, attack a program meant to help the parents save some money, attack the thematics meant to provide training tournaments, attack the juniors till they break down, it tells me something about their character.
Is it surprising that they can now lose to players who are around 2100? And is it surprising that they will find tons of excuses to hide their failings? So can that glass ceiling be breached? I think so.
