"Google would be an elephant while DuckDuckGo is a mosquito (this is not to emphasize; I’m actually making things better for DuckDuckGo)."
Why would this guy go out of his way to say this metaphor is actually literally informative and generous towards DuckDuckGo while apparently having exerted no mental effort and being incorrect by orders of magnitude on his own data?
If you're most generous to the writer, you get 12 million hits /day vs 13 billion hits /day according to his data from Wolfram, for a ratio of ~1/1100, which applied to a pygmy elephant of 5500 lbs yields a corresponding weight of ~5 lbs for the mosquito, or over 2,000,000 mg, versus the average mosquito weight of about 5 mg. Even if he meant a small 2000 kilogram pygmy elephant and a 20mg elephant mosquito, he's still 5 orders of magnitude too generous towards Google in mass comparison in his metaphor in which he is "actually making things better for DuckDuckGo".
I think most people think of animals like African Elephants when they hear "elephant", though, in which case you're looking at a 13,000 pound animal versus a ~12 pound one if you use hits as your metric, or a ~95 lb one if you go by visits as your metric.
So an actually fair metaphor is if Google's an elephant, DuckDuckGo is somewhere between a goose and a hyena. Better watch out, Google.
