It's not like the Cleartype tuner actually does what the pages claim - you can go through and use the magnifier to choose the grayscale-only outcomes and still see Windows doing RGB stripe cleartype throughout. People literally have to install third-party tools like MacType or GDI-PlusPlus to get solid font rendering. So blaming users for using it wrong (especially when they're not even on Windows) is odd.
Also, many people can see and are bothered by particular non-rectangular pixel layouts - it doesn't require doing odd things.
