As you said it depends on the context, I agree, but thus the chances someone's using a generic query to find vendor independent resources like blogs are not zero. With regard to the given example "nrf wifi", I'd prefer DDG's results as I usually know the manufacturer of the hardware I work with but often search for solutions to problems in context of that hardware. Furthermore depending on familiarity with domain names it's possible to deduce the manufacturer's website from GP's 9th result on DDG.
