I don't know reliable numbers for this and I'm not sure they exist. Would love to hear though! But just take stock of your surroundings. Think of everyone you know, and think who of them sideload apps on a regular basis. Now correct for the tech-affinity of your social surroundings (probably high if you hang out on HN...) For me, only the most hard-core of my friends sideload at all. Everyone else goes with stock apps. So sideloading should be in the regime of "count the zeros before the first non-zero mantissa digit."
