@rodhilton Feels strange defending the old Googy, but... Google Search was never meant to be the source of truth. It is what it is: a search. If you create a text file somewhere on your computer with "2x2=5" in it, and then do a search for "2x2", there is a good chance the top result would say "5".
Of course, they still feel pressured to correct this result (and they did), but maybe it would be better if they didn't. Providing somewhat accurate information is Wikipedia's job.
