Apple uses grayscale font rendering too, not even pixel aligned. It looks nice because all of their devices are high DPI.
Microsoft do know what hardware people use (in third world country I would say 99% of people do use low dpi monitor), but they changed and ruined people experience anyway. That is the main point, they don't care about existing user.
I bet if apple monitors was low-dpi monitor, apple would do everything they can to improve font rendering in their low-dpi monitors.
Do you see the mindset?
