I think it's important to make a distinction between the restrictions imposed by law and restrictions imposed by the seller.

For pretty much every thing there are restrictions on what you can do with it - if I buy a phone, I'm prohibited from smashing it into my neighbour's face, and grinding it up and baking into the cookies I sell would be a violation of health&safety rules, but that's still full ownership.

Now, if the seller wants to impose extra restrictions above and beyond what the general society does, that's a different issue.
