I'm an engineer. started it mechanical/materials (1980s), switched to electrical/computer/systems engineering in (1990) then software/architecture (1998) and now defining a product'/business' tech architecture.
Never had those issues you rant about and because of my position, I know at least 100 Iphone 6 users.
Do you want to call me, and others like me a liar? Seems that would be the logical extension of your rant.
Bending never was, and still isn't a significant issues. My glorious anecdote (because they're so pertinent in general... (sic)) and tech and business reporting since then (a bit more pertinent) and Apple's own filings (very pertinent), seemingly bears this out. Meaning you don'T have hundreds of thousands out of 200M with the problem (even at that unproven high level, this would only be a problem that hits 0.1% of all Iphone 6).
Doesn't mean bending never happened (if you sell 200M phones, just about everything may have happened...) or that your specific phone isn't a lemon. I'm going to give you that one, and nothing else because here, your own personal experience trumps mine.
Doesn't mean they can't make it tougher, or more rugged. Why not if its a differentiation point. Its even possible they wanted to switch to 7000 aluminum for several years; the watch project was then a good way to get the process right. They wouldn't want to have production issues in a product requiring huge volumes like the Iphone.
A switch like that is not something you would spring in a few months (considering how much harder it is to machine the new aluminium vs the new one), which makes the current possible switch more a long term project than a knee jerk reaction to a non event that some purports it to be.
