Poorly designed because there were large number of similar problems and they were not fixed in the 2017 and 2018 iteration. It is not subjective, but objective truth. And it isn't just about the hinge.
Prior errors, even if we accept that, doesn't make every incident evidence of poor design.
I'm saying that the evidence of this "flexgate" being a design flaw is incredibly suspect. And it's worth noting that soldered in memory, hard drives, and heavy integration likely improves the long term reliability of those connections, in the same way that a display-connected ribbon cable removes one more point of potential issues (yet another connector interface).
Having said that, I absolutely think that Apple should offer a three year manufacturing defects warranty to all purchases, and their one year warranty (geared to push AppleCare+ which is priced primarily to cover the accidental damage coverage) is ridiculous for a high-end piece of hardware.
