Interesting. I agree with everything you wrote until the last sentence. I think he made some great arguments against TDD, but none against unit testing.
> Test-first units leads to an overly complex web of intermediary objects and indirection in order to avoid doing anything that's "slow".
This is an argument against unit testing (and is a good example of the conflation). Personally I do TDD with slow, system tests, that mainly are testing business requirements.
He makes a couple of points that some TDD people are rabid, but that is just an argument that some people are jerks. It's not an argument against TDD. (And exactly the same is true of Unit Testing).
