So at worst you can complain that existing equipment may require an adapter. That seems like a fair price for progress to me.
Standards change, but at least this one hasn't changed very often. I think "once" is an allowable amount of change.
Samsung did it at least twice before Apple switched to Lightning, another time after Lightning and will probably also move to Type C soon. Same for HTC, they switched port choices before Apple did as well, the HTC Dream has a different USB port than the HTC Evo and both came before the iPhone 5, and they're also likely to change to switch to this as well.
So basically Apple is the only choice that comes closest to behaving as you expressed a desire for and instead you shit on them out of complete ignorance. Good job.
Samsung also had USB3 Micro-B (the wide connector) on the Galaxy Note 3, but went back to a regular Micro-B in the Note 4.
Samsung and most other Android manufacturers aren't even guaranteed to maintain physical dimension compatibility between different models of the same exact phone (S6 vs S6 Edge, for example), let alone if you were to just stay with Android as an OS and were switching between manufacturers each upgrade. No way in hell you're keeping any nice-fitting docks or cases around for more than one Android phone purchase.
Their delayed support on NFC arguably killed the user adoption for the tech as well, but i digress.
