there will always be someone struggling with something. Regarding display, this issue will go away over time with high DPI screens.

In general it should be noted that some of the burden on making content accessible is on the side of the tool presenting the content. So instead of avoiding the use of a certain font options should be considered like:
- use of a viewer that does not use ClearType
- increase text size (should reduce impact on ClearType induced problems)
- (temporarily) switch to grayscale display (should reduce impact of ClearType induced problems)
- use of text customisation functionality where text content is shown based on user controlled styling
