On reflection (being an engineer) it makes sense this would happen even without malice. Engineering teams on existing products are incentivized to keep innovating. It's ideal if you can reinvent a part of a product or process while maintaining functionality but often it's easier to get an 80/20. So, a large number of small corner cuts reduce overall quality and costs. If in fact you try to increase functionality, that's actually a new product. The inevitable S curve of profits from any given product means businesses are incentivized to move improvements to new products, leaving old ones to be cut to death.
