This from a bloke who said stoner would just have to learn not to complain when rossi kicked his ass, both of which were apparently exemplified by the jerez torpedo last year and stoner's reaction to it. His alternative tactic of almost always kicking rossi's ass fairly severely since then would seem to have been rather effective.
It is fairly clear from what he has said in the interviews pertaining to his retirement, to all but those who exemplify the attitude involved, when and why stoner became disaffected with the sport . He would seem to be unaware himself that he wasn't genuinely ill in 2009. Just supposing he was actually ill, the general reaction from those of your ilk, ie that he was faking it, then proceeding to viciously gloat about him being "mentally broken" by the marvellous one, may have felt just a little unjust. That his team (or their major sponsor anyway) to whom he had shown great loyalty and brought unprecedented success, bought in to these fantasies and immediately wanted to ditch him on their basis perhaps may have also not appeared entirely fair.
I think he had a burning desire to prove all you guys wrong, and has done so. From my perspective it would have been cool if he had continued to do so for several years, but if he doesn't want to, he doesn't want to. For such people to now claim that he owes them thanks as seems to be your current contention is a bit rich, imo.
Btw, that other rider who is his antithesis and exemplifies all that is good and pure about the sport has now left 2 teams on bad terms because they didn't show him the proper respect or something, is in the process of trashing a 3rd, and just 2 weeks ago more or less said the sport which has given him much more than it has given stoner was boring and that everyone should watch wsbk.
