I'd agree if Apple didn't try to make it impossible for users to change their battery!
Making the thing hard to open, gluing everything inside, charging $90 for swapping and putting too small batteries in their phone is ground to sue alone.
Apple is going out of their way to try to get people to buy a new phone instead of fixing the one they already own, and they are known for it, so this is just the straw that broke the camel's back.
Since people are too stupid to vote with their wallet, someone has got to do it. And I hope other's will follow, and not just Apple which is probably the worst offender but definitely not alone.
All electronics should be fixable, batteries should be accessible and changeable without voiding warranty. Repair guides for repair shops should be mandatory. Connectors (and chargers) should be standard.
And here comes the car analogy: if apple made cars, you could only service them in apple garages to fit new apple tires and apple brake pads. Does this sound reasonable?
