No legal precedence, sorry.
I wrote the #HackingLicense (with the help of a lawyer) to address the issues I see in mainstream #copyleft such as #GPLv3 and #AGPLv3.
These were my first choice before realizing their limits in protecting all evolutions of a covered work.
Few projects use it, mostly because I'm involved. For example https://github.com/hermescenter/monitorapa
