I haven't read any books in years because of how shitty iBooks became.

I used to read a lot, on my iPad, iPhone, Mac.. until a few years ago when iBooks (right about when it became called just "Books" I think) started rabidly deleting your downloaded books, even if I have 10s of GBs of free storage on device, and keeps having to redownload the books every week or so, so it's useless when I want to use it the most: away from home where there's no internet so no other entertainment, on flights, or long drives..

Just like Apple's other eternal shitshow Siri, you know it won't work when you need it so you never try again.
