Maybe on the individual level, but the aggregate effect is that manufacturers are incentivised to save money by increasing reliability. Which is a good thing for everyone.
But honestly I've had Macs that still work 15 years after I bought them, and iPhones that work for easily 6 or 7. That's not because AU or EU require a somewhat longer warranty, I don't think.
The EU mandates that in the EU you can change your default navigation app from Apple Maps to Google Maps.
The US isn't getting to free-ride on that, that only works if you move to an EU country.
Why wouldn't apple do the same for US vs EU, if EU has a longer required warranty period, apple can bin processors so the US gets more likely to fail processors and the EU gets more stable chips.
It would be the sort of vindictive malicious compliance apple has been doing with everything else, so I wouldn't put it past them.
2002 PowerBook user checking in. Not great for "modern" work, CPU gets really hot compiling "simple" stuff like git or libressl, but OSX 10.5 is a superior user experience to macOS 15. Still great for lightweight web browsing (disable JS!), some coding (Python 2.7.14!), classic games (StarCraft! from a *box*!).
