Interesting, was it always that way for you? I feel like for me with books printed on paper I’m actually a lot less picky but for e-readers (or any text on a screen really) the kerning, text size, etc. matters a lot more. The impact is definitely more pronounced for regular screens than e-ink though. Text size I find has the biggest impact on readability on screens for me in general.
Poked through the site a bit and found the direct link to the Bat House Builder’s Handbook for anyone else interested!

Sure, but the bacteria they’d be used to from back then would probably be fairly different from the bacteria we’re used to today.
