During a visit to a factory in China in May 2011, I took this picture:

As you can see, they were producing digital verniers for various well known brands. This factory is regarded as one of the best in China, with a comparable price tag. ARCs Premium Height Gauges come from the same place. ARCs callipers come from two other factories, rather than this factory, for various reasons. Most of ARCs calipers are now fitted with CR type batteries.
The factory which is making for the above branded companies, is making to the said brand owners requirements. The said factory has its own grinding facility in-house to make the mechanical parts. Many other such assembly factories buy in the metal components from various places. The plastic bits are always outsourced by ALL Chinese factories, and the circuit board is sourced based on price and requirements of the brand owner. ALL Chinese factories in this game have to buy in the circuit board from certain recognised makers. The quality of circuit boards and components/specifications required, can be good, bad or ugly, again depending on the customers requirement and price paid.
The You Tube video which may be accurate, presents a limited simplistic view. There are many factors at play, to include cost of components being used, quality of mechanical and electrical components being used, and which batteries are being used. Yes, Mitutoyo is by far one of the best, but if you regard them to be 10 out of 10 for quality, in my opinion, some Chinese origin factories are around 7 to 8 out of 10 vs the Mitutoyo, going downwards to the Aldi levels of around 4 out of 10 in comparison to Mitutoyo. This is all reflected in price, and generally if you accept this, then there is a place in the market for digital verniers at various quality price levels. The Aldi ones may meet certain peoples requirement for the price paid, but please avoid comparing this or the video with the M&W budget, because the M&W budget has been made to far better specifications than what has been presented in Aldi or the video, one way or another!
