This whole fiasco is part of what motivated me to move out of the Apple ecosystem. The other part was the abandonment of the headphone jack.
If the phone was only going to last a year without becoming unusable unless it was throttled, then that's terrible design. If they slowed down old iPhones to drive sales then that's fraudulent.
Either way I'd rather not be in an ecosystem that only has one manufacturer that conducts business that way.
