With some technical devices it's not that easy to change the default properties of a font. Which means that some of us need to have at least three pairs of spectacles and a magnifying glass, otherwise all fonts become kind of like wing-dings and any attempt at comprehension goes down the drain to a cesspool of frustration.
I'll not be blaming anyone for this unnecessary expense, because given the
nervous condition of nation states around the world, and their own access to
technical devices, laying down blame can lead to suspicion of, and poor grades
for, us citizens. I'm probably running at a D minus at the moment.
