We’ve been keeping them improperly in the winter since the mid 20th century, leading to unnecessary bee mortality within hives. Whether that’s torture or not is up to you, but it’s definitely unnecessary harm.
This is suggesting that we should be using hive covers. What exactly changed in the mid 20th century?
We stopped using hive covers because they’re more expensive than the increased mortality. They naturally nest in tree hollows in winter, whose thicker walls (and living material) allow the hive to maintain a higher internal temperature than uncovered hives (or covered hives).
