Any user should be able to walk away from the original hardware vendor, never contacting them again, and still be able to use the product in a normal way. Otherwise you bought a service, not a product.

Sure, if that's what you actually paid for.

Sure you can walk away from Apple completely like 80% of the world does.

I would take a different stance on where consumer protection should be heading. The problem with previous Google Pixels was that Google walked away too quickly. You still have access to the app store, you can also side load, and apps still work. So what's the problem?

The problem is that a phone which doesn't receive regular security updates is unsafe in the modern age. People use this device to deal with their bank and make payments. So instead of talking about how the user can or can't walk away from Google, I'd talk about how there ought be policy which prohibits Google from walking away from you.

In a sense internet security is a service and not a product because your phone isn't secure without updates.
