Hardware companies by and large don't get software. They just don't understand it. Their world is sourcing parts and assembly and packaging. They look at software like any other line item in the BOM: Like a screw or gasket. You source it from the cheapest supplier, and spoon it onto the product somewhere on the assembly line. These companies simply don't care about their software, and their requirements to their supplier amount to "make something work." The quality bar is literally "customer should not return the product."
