Correlation does not imply causation: Yes, it might be true that companies make changes to their products that break stuff somewhere else. But to claim that it is done intentionally is very far fetched. Especially when you have to support so many different environments, it is close to impossible to thoroughly check all of them. Demanding that the performance is good even goes one step further than just demanding the service works.
