All the ai features can be disabled. Plus most of them only activate when you tell them to do something. Not sure what your point is.
Settings, galaxy ai, disable everything if you really want to.
If you care about privacy, enable "process data only on device" so your data never leaves your phone. Enabling that will also disable any ai features that cannot run on your device without using samsung servers.
So to counter your points.
Most of the ai features only run when you tell them to. If you never use them they never do anything or send any data anywhere. Eg, ai spell check and image generation never do anything unless you press the button to use them.
When AI uses a server, it is secured in transit, secured on the server and wiped when the server finishes using it. No clue where you got unsecured from, it is definitely secure. Could the server itself potentially be hacked or store things? Maybe, but you can use process data only on device to never use samsung servers.
There is no data theft, you are told exactly what each feature does when you enable it. Don't enable what you don't want to use. For the s25 series, samsung literally created "personal data intelligence" which is a software system that keeps all the ai learning locked to your device in a way it cannot leave.
Ai when ran locally on your device is fully private, even works without Internet. When using a server, yeah potentially not private but you can again process on device.
