Nah, assuming lack of satire I don't think it was harsh at all.
It sounds like the person HAS some experience, and that experience has taught him about TDD, Unit Testing, naming, etc. and they decided against all those things as simply slowing them down from doing their thing.
A person following these guidelines would generate more work for others than they would solve with their own work, i.e. they would generate negative effort towards solving problems. Simply having them not be around would make any company do better.
This would highlight a problem with personality rather than lack of experience.
