I have owned many, many Apple products for 30 years and have never had to send one back to the factory for any reason.
If the windshield on any of my cars breaks, I have to get it replaced by a specialist, but that is pretty normal. If yours breaks do you replace it yourself in your driveway, using no tools other than a fingernail file and some duct tape?
I actually do replace my own windshields, and the tools are surprisingly rudimentary - a long piece of flexible metal and a couple of sections of broomstick on the ends of a metal cable.
I’m in IT and have had several employees break their Apple devices (iphones, typically). I have the ability and tools to do the repair, but Apple won’t sell you the parts to fix it - you have to send it back to Apple if you want Apple parts to do the repair.
