What the hell?

"This potential for bending is of course not unique to the iPhone 6 Plus, with reports of bent iPhone 5 and 5s handsets surfacing in the past few years. As iPhones get thinner and larger, however, storage of the handset in a pocket becomes riskier."

I don't recall any Samsung or HTC owners (who've had considerably larger phones for a while now) reporting this sort of thing.
