The amount of monthly contributions has doubled in the last four years alone, from ~7k to ~14k commits per month. Why did I take six years as a reference? Because 2020 is the year nixpkgs really started to pick up traction, and the growth has been almost linear ever since. Your argument only holds if I were to say "it grew to its current amount of monthly contributions in 2020 and then stayed constant, without growing any further."
