Javascript size is a weird metric, and the plot is useless without context. The plot does not even state for which browser the metric was collected (or is it the repository size? That would be completely useless, as uBlock's and uBlock origin's repositories include versions for different browsers.) Because when I add the sum of all .js files in uBlock's repository, I get 1.08MB. Heck, the whole src and platform directories combined are 2.8MB, and that includes both the Chrome and the Firefox version! Can you point to a source for that plot?
