This cold storage is a significant added cost and used only in hot areas . It minimizes varroa since the mites can only breed in hives with brood. It's done in spring when otherwise the bees might swarm. Failing to insulate hives in cold areas will require more feeding to maintain colony size over winter, and that would be financially dumb.

The writer seems like an expert, but makes weird assumptions. Commercial beekeepers are very different (and care much more about costs and output) than hobbyists. Some hobbyists are no doubt incompetent (but caring), and some commercial operations are completely uncaring (but rarely incompetent).
What I have heard is that they use less food when it it cooler due to their metabolism being lower.
It's a cost add in the warm climes so the only reason I can see to do it is for mite treatment.
Sometimes it seems that this kind of philosophical narratives are anchored in XVII century science. Everything with pain receptors feels pain. Period. Animals evolved this structures exclusively to feeling pain. Because this is a very positive trait if you want to survive.
Insects and other invertebrates are known to have pain receptors since the XX century (Yes, clams feel pain, and roundworms feel pain also). This is not new ground breaking science at all. What is new is using this to move forward the agenda of the cruelty animal crew.
I'm not against building better beehives, but we should focus, --laser focus--, our attention and most of all our scarce resources investing into much more urgent problems with insect species losing of habitat, being poisoned and facing extinction.
Because money is scarce on conservation and much more scarce on invertebrate conservation; and "give me money or this bee will die frozen two days before to just die of old age and be replaced by other bee" is a ridiculous problem.
XVII century -> 17th century -> years 1600 to 1699
XX century -> 20th century -> years 1900 to 1999
Yet they'll never know real pain like the devs in deadend or overworked jobs.
In such a scenario, deliberately causing stress generation after generation in a species crucial to our well-being and, perhaps, survival is not advisable. It raises the question: What could go wrong?
I will say that this article together with one from earlier this year [1] put into question the benefit of cold storage.
