Denying a historical phenomenon for political gain is as bad as selectively citing a two century old book to justify xenophobia. It is revealing that the author mentions Tainter's "Collapse of Complex Societies", and then dismisses it's meticulous definition of collapse as "jargon". Before coming up with this definition Tainter spent a whole chapter describing many, many examples of social collapse including the ones mentioned in the article. The definition arises from these examples and absolutely covers the collapse of Rome, Bronze Age and others.
As for how we define and study the social collapse without arbitrarily designating some cultures as superior to others - a good example would be collapse of ecosystems. In this case you can have a sensible definition of complexity and energy intake and the collapse would be a sharp decline in both. There is a whole framework for similar studies in social collapse - see this talk.
