Now that this issue is Apple vs. Google, the discussion has turned into a huge number of namecalling arguments with conflicting upvotes vs. downvotes.
My take:
Patents need a MUCH higher bar than what's currently out there. Eg. RSA patent = VALID and the Apple patent of using accelerometer to rotate a display, but-on-a-mobile-phone-instead-of-camera = LAME & INVALID.
Kind of going off on a tangent, but Android didn't bring nothing much new to the UI(except maybe notifications?), it's mostly a pale imitation of iOS. WP7 on the other hand, atleast has an innovative mobile UI in the form of metro.

Some android apps are copying it verbatim...
Apple zealots
Mostly rational people who prefer iOS
Mostly rational people who like both
Mostly rational people who prefer Google
Android zealots
There should be some way algorithmically to determine the people who are in the extreme categories, say...
extremism quotient:= (|upv| + |dwnv|) / max (1,|net score|)
Then if that exceeds some threshold over a certain period the person's votes could be ignored or diluted.
