I wholeheartedly agree that people can't agree on what "unit test" means precisely, either (even though I think your specific examples are a bit disingenuous). In particular, classical and London-school / mockist TDD have rather different definitions of it.
That's why it's important to have a well-rounded test strategy with different types of tests that have different purposes, instead of using some blanket approaches.
