I'm amused that they skip Harbor Freight despite it being an industry colossus through sheer volume. It's like trying to write an article about what grocery stores sell what brands of milk and skipping Walmart.

And before anyone tries a "no true tradesman" fallacy, go ask some people who work in the trades. There are select items they likely buy from harbor freight, probably not any "required to do the job" battery powered power tools but lots of hand tools, consumables, shop equipment, etc are likely sourced through them.
