Re: OK, it's very rare
Per Consumer Reports — see e.g. http://www.examiner.com/article/consumer-reports-says-iphone-6-and-iphone-6-plus-are-not-very-bendable — the iPhone 6 is in fact no more bendable than the competition.
From worst to best:
HTC One (70 pounds to deform, 90 pounds to separate);
iPhone 6 (70 pounds to deform, 100 to separate);
iPhone 6+ (90 pounds to deform, 110 to separate),
LG G3 (130 pounds both to deform and to separate);
iPhone 5s (130 to deform, 150 to separate);
Galaxy Note 3 (150 pounds both to deform and to separate).
So Apple has remained strictly within industry bounds, never producing either the most robust or the most deformable phone. Maybe the issue is more that it's jumped from being equal with the high end of the table on one measure to being equal with the low end on another?
