The whole "misery" concern is hypothetical and it fails to hold in practice. Jet engine noise drowns out normal conversation volume. I'm younger than most on this forum but I still remember seatback Airfones.
Airfones were quite expensive to use, so conversations were short and rare. And I'm sure you've noticed that they disappeared long before in-flight wifi became available.
The annoyance factor is real and
scientifically verified.
