@LAC I don't know if it's cool to ask what now a particular bootfitter charged for something in public. I'm just wondering if this needs to be a full couple of hundred dollar scale alignment cost or if this can be more minor. It sounds involved like it would cost a bit. You can PM me the answer it if helps or I maybe I should just contact your fitter. Anyway thanks for the helpful details.
Well I was trying to resist arguing the point more, but ok.
In LAC's picture above, you can think of it two ways. In his picture the leg remained the same and he tilted the ski. (I assume the leg is a natural position in both pictures)
You could instead consider what is required to ski with a flat ski in both cases. In the first picture, of course is if your leg is in natural stance (knee tracking naturally) for the tilted ski, for that setup you have to tilt your leg(s) to get a flat ski (and you WILL). So the leg is missaligned on a flat ski. Or the ski is missaligned on a straight leg. You can say it either way. That's not the important point but it does seem to cause needless disagreement.
In the end by the second image what he has is a presumably straight leg and flat ski BUT he still has a tilted foot (it's right there in the picture, red line). Unless he wanted a tilted foot to correct some orthopedic problem, then this is not natural. If the leg is straight and the foot is tilted then the ankle is bent, and the ankle bend is controlled by cuff alignment.
There are two "joints" between the leg and ski that determine the ski angle for a natural leg position. One is the ankle, cuff angle, and one is the hardware on the bottom of the boot,(wedges or whatever). You can fix the ski with either one. This Salomon situation is a perfect example. There is no question my ski is tilted because the cuff is tilted 3 degrees out. The cuff is tilting my ankle and is tilting my foot and ski relative to my leg. There is also no question it can be fixed by adding a sole cant, because I can certainly stand in a way that looks exactly like LAC's first picture. There is also no question that just like in LAC's picture, this will (does, you can just look at it) leave me with a slightly tilted foot. In any situation where the footbed was originally parallel to the ski, then canting the sole will leave you with a tilted foot when the ski is flat. If you wanted to then that's fine, and even if you don't I'd say it's not so bad, but I don't know why you'd assume that's the "right" way to fix the ski when it's at least as likely that the cuff alignment is the right way, as it is for this boot on me.
It's funny that on cantology's web page they mention that fixing the ski angle by changing cuff alignment will make your ankle out of alignment. Of course that assumes your ankle was in alignment in the first place. If your leg is straight but your foot is tilted as is presumably the case in LAC's first picture, then you had a tilted ankle.
Of course cantology cannot sell cuff alignments, only wedges. I really have to wonder if that has affected the bias in the way of thinking about these things. (edit: I don't mean to imply dishonesty on their part or anyone else's. Ways of thinking about thing just spread sometimes and probably that's not even the case. I've seen many posts saying that canting is used to fix angled ski problems and cuff alignment just fixes the cuff alignment. As far as I know many people use the cuff to edge the ski which is why lateral flex is an issue.)
