Mixing the car radio and actual critical systems (backup camera) doesn't seem like a great idea. Especially when the car manufacturer doesn't control the entire system. I know nothing about the supply chain for car radios, but I wouldn't be surprised if it was all made by some secondary supplier, so Mazda doesn't even necessarily have the code to the section they need to patch.
But, I'm honestly more surprised that it's a Mazda specific issue. I would have expected for the same bug to hit multiple infotainment systems.
