A shorter example:

git clone https://codeberg.org/yourname/yournewrepo
cd yournewrepo
git reset --hard abcdef1 # commit that you want to reset to
git push --force origin

Note that instead of abcdef1 in git reset you can also use the regular expression syntax. So if the commit was named Last release before unwanted changes you would say git reset --hard ':/Last release before unwanted changes'.

I also personally changed to the EUPL where I would normally use a GPL. As I understand it the EUPL aligns more closely with actual (European) law. Recent events have persuaded me to alugn more with that than theoretical US law.

That depends on the license. Music is also available on Youtube without authentication requirements but I don't think you can just download those and do whatever you want with them.

Right, so you can't "enforce" a return from the function.

shouldn’t Rust enforce returning from function

How do you enforce returning from exit or a function with a loop that never terminates?

You're kidding yourself if you think most people in this thread are actually programmers. Most people here wouldn't know the difference between C and Rust code if they saw it, let alone be able to write anything in either language.
