You might be nearly the only person who wants to watch films in this manner.
I would have to assume that there are plenty of people who would prefer it that way (Like some of my weirder friends who have no care for quality of presentation, and I’d guess mostly pirates), and heck, even Stanley Kubrick hated letterboxing, and that’s why he shot all of his films (after Clockwork Orange, I think) in open-matte.
