I think rather than the font it is the picture size, or at least previous chapters would spread across the screen for me which in itself would make the font look larger, this one takes up maybe half the screen. I mean I can read it but I do understand why people would get annoyed. I guess they could go to your website and get it and it should be the uncompressed version. though admittedly that would be a dirty trick to force people to go to the website if done on purpose. (Which I do not believe is the case)
