I do not really think that 'people go against' Yuzuru 'just because' of programs - people actually have a right to feel disappointed and express it, but I do feel that the disappointment have nothing to do with going against Yuzuru in 'personal' sense, like turning backs to him at all.
What is totally unnecessary there (but totally expected tbh) is getting ballistic and war-mode over simple disappointment expressed by some over Yuzuru being back with both his already used programs - at some point, we have to realize that we all have some expectations, dreamy programs about skaters and with such figure as Yuzuru it's all so much more intensified and facing such announcement triggers disappointment, NOT necessary critique/negativity, but is received as such (wrongly).
Myself, I see Yuzuru as one of very few figures nowadays that gets the sport going - but it is due his work ethics, demeanor and perfection strive, not by his programs necessarily. Saying that, it depends what point of view we take on about voicing opinions over return of Chopin SP and 'Seimei' FS, because different people seeing him and feeling him differently as a skater, as a person. As a casual viewer, do I feel a pang of disappointment and kind of longing over the fact of old programs return? Yes, because I simply associate new season with chance to see something new, fresh, challenging from skaters and with Yuzuru - it's also connected with expanding his great interpretation talent regarding various types of music/themes. But do I 'go against' Yuzuru because that choices made? Absolutely not. People really have to understand that voicing a mere disappointment/critique over sole DECISION to re-use programs/music has nothing to do with going after skater who made that decision himself.
From my perspective, I respect Yuzuru's decision - even if feeling disappointed by it. My disappointment though is sourced more form the fact that this could be his last competitive season and would love to see a new stuff just for sake of 'utilizing' his musicality/interpretation talents, a stuff (hopefully) to re-watch and remember for many years; it's not really about perspective of seeing again Chopin SP and 'Seimei' FS, because those programs were very impactful and thrilling to watch as they already were. After all, this is an Olympic season and Yuzuru decided what was the best for him all factors considered, looking at his path after Sochi - he's conscious about himself by making those decisions and he probably is aware that such decisions alone won't make you fans, but the actual programs could. Let's wait. If I have a faith and confidence is something in that situation, it's Yuzuru.
And now it's more about if this announcement/decision made will overshadow people's reception of actual programs Yuzuru will present upcoming season - it's a thing Yuzuru himself has nothing to do.
