There are downsides to both formats, but with paper there's no company keeping track of the date/time I open the books on my selves, or how often I open them, or how long I spend on each page, or how long I take to read the whole thing. I also don't have to worry about the books on my shelves being remotely and silently censored or edited. I don't have to worry about ads being inserted into them and I can freely read them and sell/loan them to others long after they've been banned.
