Please stop using the word "right" in this context.
If I break my phone (or camera or tv or vcr or dvd player or headphone etc.), I CAN AND WILL bring it to a repair shop. Yes...they may tell me that I broke it myself and thus warranty will not cover it. Fine. But I still have the right to physically walk into a repair center and hand them my phone and ASK if they will repair it. Heck, they might even tell me no because they don't want to work on phones that the customer dropped in water or left in a microwave or opened myself. Fine. Just like some car mechanics don't do oil changes (seriously...because it's not worth their time tying up their business/time with a low-cost service).
As with any product I own, it's mine. Period. I can dismantle it to my heart's content. If I break it, shame on me. And of course if I break it I wouldn't expect a FREE repair. I would expect, however, that a repair shop would STILL FIX IT FOR A FEE.
Moreover, this video mentions that numerous Apple customers go to Apple for the repair and Apple is REPLACING the normal, standard screws that were on the PRODUCT YOU OWN with new, non-standard screws. That's totally wrong. Ethically wrong. The equivalent of bringing your car in for new tires and they weld the lug nuts on (because, again, there is no tool for you to buy to maintain the tires yourself) after giving you new tires.
