There should be no reclining.
I strongly disagree! The straight up angle of the seats causes me very bad back pain. Just that little bit of recline is a lifesaver for me. You want to see a viral video? Take away my ability to recline on flights. If they just had the default position reclined just a couple of degrees, it wouldn’t be an issue.
I take great care to make sure I choose airlines and rows with reclining seats.
