No actually I agree with you, plus PDF is a privacy and security nightmare allowing for arbitrary JavaScript execution by default if you don’t limit its permissions. but unfortunately it was all that I could find of that ISBN so it was either shut up and use them or pay full price for my textbooks, so, y’know, I sort of grit my teeth and went with it.
PDF is super overkill for ebooks. Mobi or epub are usually <5mb per book (usually around 1mb)
