Most people are using computing devices to do the specific things the device is designed for, quite often in a low-trust high-security work environment (even when this isn't explicitly how people think of it, it's usually the case - i.e. bad things happen when unauthorized access takes place). For the vast majority of people creating barriers or guard-rails around what their device can do is actually a win. People and organisations often put a lot of effort and expense into creating even further guardrails and restrictions a lot of the time.

There are hobbyists and professionals who take apart, repair and/or modify cars but it's also generally a very good thing that you can't just make (or easily authorise someone else or their product to make) significant modifications to how your car works. The walled gardens are really just computing growing up.
