I do. I'm happy to pay for Actions minutes on private repos, but I do worry that they'll change their policy with regards to free minutes for public repos at some point.
I felt a lot better about my git scraping work (https://simonwillison.net/2020/Oct/9/git-scraping/) after GitHub released https://next.github.com/projects/flat-data/ which was inspired by that work, as it feels like it's now acknowledged as an OK use of their platform.
I'm hoping people don't abuse shot-scraper too much in terms of saving huge binary files to free repositories - that's why I haven't yet included tips on running scheduled scrapers in the shot-scraper-template documentation.
