Thanks @linsui ! Very interesting. And sad, but not too surprising, to see how many are still on Microsoft’s github and other proprietary, or non GPL systems.
To others who also may not know intuitively, “just open in an editor and search” means first download https://f-droid.org/repo/index-v1.jar (mentioned various places including here: APIs for All The Things! | F-Droid - Free and Open Source Android App Repository), using an archiver program or unzip command to expand index-v1.jar or extract index-v1.json , a 26+ MB file; then having an editor program and computer that will search and display counts in a reasonable amount of time. This does not include Mousepad, less, vi or nano with default settings on an old Thinkpad. For me it would probably mean using some sed and grep, and patience.
