That's not really a fair analogy, Windows isn't that locked down. It's more like the hood is open and for general maintenance you're fine, but all the parts are proprietary so if something breaks, you can only go to one manufacturer who controls the entire supply chain for that part. However, the parts are generally okay quality so for most people who just drive A to B, they're unlikely to encounter too many issues.
Linux is a kit car. You can pretty much build it yourself or have one preassembled but either way you can rip any part of it out and replace any component with anything you like, entirely within your control. Most people wouldn't have the competency to build one themselves because most people don't really know how cars work but for those that do, it's the dream.
I genuinely don't believe that one approach is better than another, but I do believe that the majority of folks out there want something that "just works" and Linux is usually not that option. Not on the desktop.
