Stuff and nonsense. Did you watch the last race in 2013, or his entire 250 career, or for that matter the first lap of many of his dominant wins from the lead when he is in the process of getting to the lead? He is not afraid of a battle. It beggars belief for me that people feel able to question Jorge's courage in any way, given him riding Assen 2013 with a newly plated clavicle, coming back from career threatening concussions in 2008, riding with 2 ankles fractured in practice in 2008, or for that matter riding after the massive high side following which he required a head CT scan in a recent race this year.
Where he is perhaps liable to criticism is that he may have developed his riding style in recent years to be too specialized/dependent on particular tyre characteristics and grip conditions, although as I have constantly argued I can't see why he (and everyone else) can't have a tyre which suits him.
