This is very much an anti-user behavior. Certainly having models run on-device is preferred when possible, but if you don't want to use the Apple Intelligence this is an anti-feature. Especially on devices with small storage capacities which are impacted the most by this.
In fact I don't want models doing anything in the background that I didn't explicitly ask them to do.
1) They have issues with the ways these models were trained. They may consider it unethical to use models trained on what they consider plagiarized material or on material that used a lot of energy for training.
2) They may have higher value uses of the storage space and compute resource.
3) They may view installation of apps and features without consent to be an infringement on running their device the way they would like.
4) They may find the general technology and its impact on society to be concerning, anxiety inducing, frustrating, or irritating. And simply not want to participate.
5) They think it sucks. Like, out just doesn't work or doesn't help them.
I'd be much more willing to try the stuff if they gave me control over when I do so LIKE THEY DID IN THE VERSION LITERALLY PRIOR TO THIS ONE.
Apple did the same thing with watchOS by the way. They forced a stupid new quick actions menu that always pops up before getting to the all apps screen and removed the app switcher. if you want to terminate non-working apps that are prone to not working, like Apple Music, the solution now is "well, tough shit."
It's my disk space, processing power and electricity. Apple shouldn't get to use it as they please
Let me juggle juggle with the small space I have the way I want.
I am personally tired of Apple and Microsoft fattening up operating systems.
