Apple didn't do this because of operator error. It's bad design and continues to be bad design.
So you take an old cable design from 6 years ago to try and prove your point that Apple makes crap cables? Nice try... You do know they re-designed these many years ago, right?
I take care of all my possessions. I've never had water damage nor cracked a button, port, screen, anything on my Mac, iPhones, iPad, etc. In this case the problem is Apple. The rule is not thousands of Apple owners all crapping all over their expensive Apple items and then docking Apple stars on their own website due to those actions. Apple makes crap cables.
Good for you, glad to hear you've never spilled anything, smashed anything, cracked anything, on any of your Apple gear. Now if only you can learn to be as nice to your cables. Every single Apple product that's ever come across my desk has had the cables mangled almost beyond recognition. Even those that baby the actual device, torture the cables. This is not Apple's fault, this is sheer stupidity of the consumer.
Stupidity is a known and common affliction these days too, just look at the average American consumer, or better yet, your average Congress senator. Enough said.
We presume that man gets more intelligent with each generation. I'm not so sure.
