AppleCare covers it if the scratch interferes with the touchscreen operation.
It’s not my position to support third party products. I’ve seen screen protectors cause damage too.
Many people (loosely referred to as photographers) purchase filters for their lenses to protect the front surface of the lens from scratches. Don’t you think if Nikon, Canon, Sony, Olympus etc. thought it necessary they’ve had built it in or provided one?
Your argument sounds like Apple has no interest in making the glass less scratch resistant. After all, it’s about planned obsolescence with batteries, scratches on screens, bugs in new iOS, bugs in new hardware etc. Too many people believe that BS and I try not to support it.
I don’t advocate for any third party products per se. I don’t like cases, I don’t like screen protectors and much more. I’m enough of a realist to understand many users disagree and feel compelled to protect their devices. But to me it evokes memories of going to my grandmother’s and sitting on sofas and every cushion was covered in thick vinyl protectors. No thanks. But different horses for different courses.
