Also, chest freezers are much, much cheaper than refrigerators. The last time I bought one, I paid around $300 for one that was quite large, vs. twice that or more for a typical upright refrigerator. Partly, I expect that's because they are so much less complicated, and partly it's because the demand is much lower.
Consumer kitchen refrigerators have a higher BOM cost. They have two separate regulated champers, auto-defrost for the freezer compartment (chest freezers typically don't), shelving, ice makers, external ice/water dispensers, ice crushers, and cosmetic features.
And the cosmetic features for a kitchen, rather than the work-a-day ugliness of chest freezers probably means a larger profit margin too.
