Dyson came under heavy assault by the vacuum industry. His book Against the Odds show the level of assault he came under because he was going to disrupt the billion dollar vacuum industry in the USA. The book touches on corporate espionage, including the fact that companies do this between each other! When Dyson approached Hoover, they wanted to see all of the details of his technology. But they wanted him to sign an NDA. In the fine print, it gave Hoover exclusive ownership of all discussed technology within the USA. If he had signed it and had the meeting in good faith they would have owned it, and killed the tech.
China is really huge in doing this. They basically setup manufacturing for legitimate products. Copy the design specs, then setup shops to product nearly identical items but with substandard (even dangerous) changes. One of the things China does is utilize low rated capacitors so they can time the lifespan of anything they sell. Another common practice is they will manufacture something for American firms, under American specifications. Then at some point later they will start cheapening the components, and substandard product will go out. Often it can take firms months, even years to discover the manufacturing swaps and by then the Chinese firm has made millions in savings. This is often why people will buy something, love it, and it lasts a long time. Then they break it, and buy the same model item, and it is horrible.
Anyone with knowledge of electrical engineering knows you can place a lifespan on almost anything by changing the caps.
