Some Trek fans are always unhappy with whatever the new version is.
One would have to agree it's far more noticeable with STiD than ST09, though. (And not because there's any very perceptible difference in overall quality between the two films, I don't think. If anything I actually think STiD is the better film.)
It sounds more to me that some people are simply hoping beyond hope that they can convince the majority of people to hate the movie as much as they do.
Nobody can "convince" anyone to hate a movie they genuinely like. Whether a movie ages well past its early delivery and hype, or ceases to benefit from an early surge of nostalgia, is a different question. It's a fact of life that nostalgia only stretches so far.
