I'm not so sure if I got what Joesitz meant by thrust their arms above their shoulders, but if it means skaters throw both of their arms(or just one arm at times) up in the air meaninglessly when they glide, I do find it very distracting. I hate it even more when they call it 'choreography'.
I think this issue represents just one subset of the greater problem of CoP's reductionist philosophy of scoring figure skating. Ever since BoP ruined CoP for me (

) now I cannot help but notice excessive elements/redundancies in a program that don't have anything to do with the unity of a performance or music, and more to do with (the attempt at) grabbing points. I am not saying that arm movements are necessarily done for the explicit purpose of scoring points...but I think the idea of an artistically cohesive program has been at least a little messed with. Maybe there is the impression that more arm movements = more complex choreography/greater performance value, but we all know how that isn't always the case. I find myself yearning for simpler programs, at times.
As others and I have mentioned elsewhere, I am very dismayed by Jeremy Abbott's SP this season. I don't know if it's "authentic", but I find his arm movements terribly distracting and a little cringe-worthy, and it's a shame because I know he is a wonderful skater who could do so much better. I often found Evan Lysacek's arms distracting, too.
Of the current ladies, YuNa is noteworthy in particular for having choreographically appropriate, attractive arm movements (as her fan, I may be biased but I feel comfortable saying this on objective terms, as well. It's one of the reasons I am her fan.

) Sometimes her arms don't have a completely continuous line of expression down the rest of her body, but on the whole I find her arms to truly add to her performances. I can't think of any other ladies to be honest. Laura Lepisto has a lot of arm movements, and a beautiful posture--but her arm movements don't seem to be doing anything meaningful to me.
So, arm movements: They can be good, but if they're not done for a good reason, I'd rather they be omitted. A program doesn't need lots of arms above the shoulders to have good choreography/interpretation, and they can often detract from the performance if done wrong.
Edit: I forgot to add, someone old-school who had lovely arm movements, to me, is Lu Chen.
