Because it gives the appearance that you care and that seems to be enough to keep selling. The only thing they've seemed to budge on over the years is DRM music. To me, while macOS is certainly very visually pleasing and in most cases easy to pick up and use, it lacks productivity potential without the use of third party software. As I mentioned, my work computer does not even have Microsoft office and stuck with numbers as my main work platform. While it's visual simplicity is pleasing to the eye, it's absolutely terrible for work flow and things that are easily found in Excel are a chore to find in numbers. Look at iOS it was definitely pretty innovative and revolutionary at first, but it's long since lost that since about version 3. Your opinions/experience may be different, but that doesn't invalidate mine. They only care about feedback that would/result in legal action (such as the iPhone batteries, even though to me they didn't need to do what they did and it's been blown way out of proportion).
