For me as a kid who loved reading and fell out of it by the time I finished school (and then re-found that love decades later), the biggest contributing factor wasn't 30 minutes of reading for school. It was forced reading of books that were uninteresting to me in the first place, and then having to engage with those books in a wholly artificial way.
There's a lot of interesting things to be gleaned from books and certainly expanding students horizons is not in and of itself a bad idea. But school reading is painful, whether it's 10 minutes or 4 hours. You're given pre-selected material with pre-selected lessons to be taken from that material. You are expected to write summaries that explain why the curtains in the foyer of this book were blue (regardless of whether there's actually a reason the author did that or if the lesson planner just hallucinated some meaning out of thin air), and then discuss obvious lessons in non-fiction materials as if there was any other purpose to writing the book in question except to present that lesson. Sometimes you're given books to read that match whatever the current hot social topic is, again without regard to the quality of the books, and then expected to regurgitate the correct opinions on that topic as if the book presented those opinions, and again without regard to what the book actually said (or failed to say).
Reading in schools is presented and treated with the rigor of a mathematical proof, and the soullessness of dispassionate scientific observation of dying rats. It should be no wonder that what that is the experience of children with reading, so many fail to find a hobby or pleasure in it. We don't seem surprised when most students don't do mathematical formulas in their spare time after learning it in school, why should reading be any different?
