Parent did not imply that nobody should use them, but maybe offered some valid points to explain why they might not be seeing a very wide adoption.
Your response seems more hostile than it needs to be.
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.
Disagree. It's like someone posting an article about how amazing horse hair toothbrushes are and someone else comes along and points out why the world has largely moved on.
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.
Did you read the original article? It is a one-side argument basically saying there's no reason at all to not use a chest fridge and the parent comment just objectively gave a few. If one aren't capable of rational thinking and be able to hold different views (ie pros and cons) simultaneously then they shouldn't be giving opinion at all. Next you know everyone holding a different opinion is just stupid or selfish or whatever.
