It can be argued that this is not directly related to e-readers, but subject matter is very close.
Many people I know are using pirated typefaces with their e-readers (we mostly have Pocketbook and Kobo here). While some argues that personal use of licensed typefaces are alright, I believe typeface piracy is as big a problem as the e-book piracy. You cannot really weight two against each other, both are important.
I am posting the article here and writing these words because I believe many here (not the regulars but those coming and going) are not aware of the problem, are not even aware that they are doing something wrong when they download that Storm Baskerville and use it.
I have attached some open source and free to edit typefaces I optimized for eInk below, enjoy them. You don't really need to pirate hundreds of dollars worth of font files to enjoy a nice garalde serif, there are many free alternatives, and while they might not be good enough for designing, they are all perfectly good for reading.
