In the last few years, people have been pointing out an emergent benefit of ink on dead tree books: there are no banner ads, no tracking cookies, no social media integration, no gamification, no information about your reading habits sent to Google's data mines. When you buy a physical book, you own it, and nothing you do with it can be tracked, monetized, advertised, or subscriptionized.
And I bet some tech bro heard that and said "Hold my beer".
