Yes, it happens. The notice gives a link to GitHub's policy. A search of HN's history ( https://hn.algolia.com/?query=DMCA%20%20GitHub&sort=byDate&dateRange=all&type=story&storyText=false&prefix&page=0 https://hn.algolia.com/?query=DMCA%20%20GitHub&sort=byDate&d... ) shows previous examples of DMCA takedowns on GitHub. One of those previous examples is titled "DMCA notice against oh-my-fish". You'll note that this submission points to oh-my-fish's account on GitHub. Perhaps some of the 76 comments at https://news.ycombinator.com/item?id=10271304 https://news.ycombinator.com/item?id=10271304 might be relevant. Beyond that, I don't know the reason for why this submission is interesting enough to draw the attention of HN readers.
