I’d buy a paper edition if it were available to “support the cause”. The last programming language book I bought the author got two sales because Amazon didn’t follow the delivery notes where I specifically said don’t leave it on the porch or it will get stolen and one of my sketchy neighbors got a free copy. Almost got a third sale as well but I happened to be home and tracking the delivery driver so managed to get it off my porch before the neighbors saw it.
