Completely true.
First, we need to clarify something you're saying wrong. Seemingly referring to the iphone, you suggest that buyers of the iphone don't own the "device" by which I believe you to mean the hardware. This is simply not true. You own the device, not the software. Software is intellectual property, and the EU has stringent laws protecting Intellectual Property.
So, let's take one European, even if not EU, example (insert your favorite author here: JK Rowling. When I buy a Harry Potter Book, I own the physical book, the pages, binding, cover, etc. That is the hardware of the book. I do not own the written word on the page.
IOS is intellectual property, and you are restricted in its use. Just like the EU restricts use of Intellectual Property.
Really? This is the comment I was referring to:
By device, then, you mean both the hardware and the software?
But that can't make sense, because software is IP, and the EU has pretty strict IP laws. In other words, the EU cares a lot about what you're referring to.
IP owners get to determine what is and is not an appropriate use of their IP. But again, this is part of what I don't like about the EU; instead of incentivizing their citizens to innovate and create alternatives, they're trying to change the IP of Apple.
