As you said, this might be a complex one to figure out. I am biased because I tend not to use customer support services (with more of a "figure it out" approach) and am confident I could replace parts myself, though the latter might be harder with parts pairing today.

Can see how people more interested in the software side of things would care about support from [parent company] though. "Lose all support if you bypass our restrictions" is the relatively straightforward approach, but the collateral damage might be quite high. In an ideal world, perhaps the network of third party repair services could take up the slack?
