There is an ASCII chart in https://phrack.org/issues/72/18_md#article which references https://arxiv.org/pdf/2008.07753 [PDF], a 2020 article showing that open source peaked in 2013. In some qualitative sense that feels intuitively correct, but I am skeptical that in the modern world filled with a zillion NPM dependencies and the cloud YAML explosion and now vibe-coded everything that we are actually producing less lines of open source than we did in 2013. Is anyone aware of newer studies that investigate this?
That is my article. The data source (Open Hub) may not be completely representative of open source, but the precise trend I was aiming to cite was hard to find elsewhere (and especially to find a graph for!)
