It's because they're very similar machines with a lot of commonality in their potential client base. Both have small electric motors and often drive belts, so the tools and expertise needed to fix them is pretty similar and like someone suggested, there may not be enough demand for a shop than only works on one or the other in your area. Bearings, brushes, and belts wear out or loosen and knowing which to replace or service is the key, as well as having the manuals needed in order to order replacement parts. Modern sewing machines have a lot of electronic controls and make fancy stitches, but at the heart of the machine is a small, but efficient electric motor that has brushes, bearings, and belts that can wear out, just like a vacuum cleaner. Electric can openers, mixers, hair dryers, and blenders, in addition to all sorts of power tools, have the same type of motors, but they are often not worth the cost of a potential repair, especially for cheaper consumer products. Questions that start with Why can often be at least partially answered by looking at who is trying to keep, amass, save, or steal money, and this is no exception because there is a strong economic aspect to the answer.
