Samsung fridges are made in Korea. i.e. not outsourced.

They're just very bad at software.

Most non high-end samsung fridges aren't built in Korea, lower-end fridges are made in Vietnam and midrange fridges are made in China or Thailand. Regardless of Samsung outsourcing they still have to compete with outsourcing firms. There's only so much demand for fridges, 100-200 million fridges a year worldwide, and most of the consumer fridges end up primarily competing on price.
