But that, unfortunately seems to be the thinking behind most companies these days...that consumers don't own their phones, among other things, in fact most manufacturers seem to want to get onto thr bandwagon, they lease right to use them.
I'm fully in agreement with you though. Phones and most end consumer devices should not be treated as leased devices.
I may need to pay for a service to fully use said device, mobile data, wifi, etc. But those services should not be locked into one provider and should be seperate from the manufacturers.
Limits on repairs and modification should be few and a void warranty should be the steepest penalty. Modifying or repairing a device should not be grounds to have that device bricked at the whims of a manufacturer.
I lease my home. Even though I don’t own it, I still have an expectation of privacy! The law protects me from having my landlord just decide to walk in whenever they want, for example.
Privacy is something everyone should have, even on leased devices. People have things like private conversations and banking credentials on their phones.
Depends on the state
That means most cloud or other "hosted" systems (which smart devices and phones have become near inexorably tied to, for the average user) offer users no expectation of privacy.
To regain this, you'd have to avoid backups to the cloud, or using any hosted service... Not easy for most users when it comes to email, or even storage. That seems to be the first logical step.
(And yes, I know end to end encryption can help, but usability is the issue for users here - end users aren't good at remembering long high entropy passphrases, or keeping bits of paper with recovery keys safe without being lost)
Our personal computing devices should have the same sort of protections and affordances that our homes have. We should have an expectation of privacy and control over our domain. We should have the rights to build, repair, and more.
If we're not leasing a phone or leasing a house, if we are owners of the phone or the house, then we should have full control to every aspect of it.
