You're applying copyright to something functional like a computer program versus a piece of art. And what these companies are doing is making the (hardware or external) functionality dependent on that copy-written computer program. So now it's impossible to modify your device without modifying software and thus breaking copyright. Take a look at the US constitution copyright clause: [the United States Congress shall have power] To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries. How does this use case of copyright promote the progress of science and useful arts? Copyright was clearly intended to make it temporarily difficult to publish information, not to make it impossible to modify machines.
