In case of some recent Windows parts, that would need to be compounded by the mistaken belief to have top-tier engineers working for them.

It's always the departments that are closest to the customer that pay the price in my experience. At one company, after killing QA, the support team created their own internal QA process. They were going to deal with the issues anyways, so they wanted to catch as many as they could first.

They have long adopted the mindset to get users as free beta testers. Long gone the tradition that quality matters.
