Well, when I originally enter it, I couldn’t find a source (thus the “(Attributed)”).

Ultimately, though, the strength and validity of a citation is based on whether there is a documented source where the person said it, secondarily if it “fits” the person it is attributed to. I’m still not able to find any definitive place where Orwell said this. That, coupled with the Wikiquote analysis, inclines me to relabel this as spurious.
