Apple in my experience has a marvelous track record with this sort of thing.
I upgraded from an iPhone 4 to X because it worked fine for so long. This summer I updated my mom’s 8 year old Macbook Air to Monterey and it works great.
And I’m starting to think about upgrading my 2018 iPad only because of memory issues with 3rd party apps dumping context when multitasking.
The fine was for not giving notice. They have implemented the same battery saving update on several more devices without any objection from the regulators because they gave notice for those.
European fines are entirely cope, it doesn’t mean they’ve actually done anything. Similarly laws like the GDPR and DMA aren’t made with the intent of being followed, just with the hope they’ll get fines or lead to the breakup of foreign tech companies.
There was no slowdown of devices; what happened is the devices didn’t randomly turn off anymore.
