I counted who wrote every change to xz, sudo, bash, tz and 19 other projects over the last year

Billions of phones and most of the servers on the internet run on code that one or two people look after, a lot of it unpaid. I went through a year of commits for 23 of these projects, and 11 of them came down to one or two people. xz is still basically Lasse Collin on his own after the 2024 backdoor, and the time zone file every phone reads is kept by a UCLA lecturer in his spare time. If I've got one of these wrong, tell me.
