Most of the negativity is on ideological grounds - they don't like that it is "opinionated" and offers minimal customisation compared to KDE. And there's some backlash against the fact that a lot of the UI uses Javascript. (Though recent benchmarks have shown that it doesn't cause any kind of performance hit.) Frankly, I don't think that Gnome is particularly un-customizable, it just does it in a different way, using extensions that you can install. I do occasionally try out new versions of KDE to see what I'm missing, and I'm always surprised how buggy/crashy it is.
