I'm not sure I'm comfortable which a critique written by an economic competitor (DuckDuckGo) that obscures its identity and doesn't disclose its conflict of interest.
If you think DDG might have biased the structure or even falsified results, fine - make that claim. But otherwise this shouldn't really matter. Otherwise we're going to go down a rabbit hole of arguing on subjective matters, like why trust DDG, rather than pointing out objectively what's wrong with the research.
