Couldn't agree more! I've yet to see a PDF that has animated ads, pops up a subscribe-to-our-newsletter modal halfway through, or even autoplays video a few seconds after you've started reading it. I mean I suppose you could do all that with embedded JS, in theory, but one of the nice things about PDF is it mostly works absolutely fine with scripts turned off.
