I disagree. Parent's comment is like me posting an article on how toothbrushes work and this guy pops up and tells me that toothbrushes have some serious usability issues because Tetraplegic people can't use them.
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
The usability issues with chest freezers are real and it's quite likely that a big portion of the energy savings is because the chest freezers in question don't do auto defrost. Plenty of people really don't want to deal with regularly emptying everything out to let all the ice buildup melt.
