Even though 1984 was inspired by this I didn't really find any significant connection between We and Orwell's work so I can safely say he ain't no plagiarist.
Matematics meets dystopian/utopian setting (there isn't a difference between the two anyways). We is unlike 1984, but similar to something like Brave New World or Fahrenheit 451 because of the overall theme of happiness. But this isn't your regular happiness, this is advanced happiness (now with math). Can true happiness and true freedom exist? Are revolutions really an infinite process? Can happiness be forced? These are just some of the questions We poses (and answers, kinda). A question you can answer for yourself if you've read 1984, though, is "Do women always drive/fuck up the plot in dystopian novels?" Pretty much.
Größtes Manko für mich war aber das doch sehr häufige und im meinen Augen teils Sinnfreie Mathe Name-Droping aber vielleicht ist das in dieser Welt auch nötig. Dafür hat mir es aber das Ende besonders angetan.
