The real justification for browser engine restrictions is not battery life but security.
If you look at any iOS vulnerability reporting, Safari is a big weakness and often the source of zero day attacks. Browsers are hugely complex pieces of software with a lot of attack surface. A large part of Apple’s value proposition is being secure. It sounds like the new approach (in the EU only) that allows additional browser engines requires specific security measures to be taken.
Rightly or wrongly device security is going to be a strong defense Apple has against some of these allegations.
Then by the same argument, it should be ok for Microsoft to prevent users from installing any other browser on Windows besides Edge because it could make that person’s device less secure…
No, a user should be allowed to take the security risk of installing whatever they want on their computers. Security-conscious users will have clean phones, and ordinary users will have phones full of viruses like their computers.
