A sticky license includes a clause stipulating that while you can modify the code and share your modifications, any modifications must also be shared under that same license. This is usually referred to as a “share alike” clause. GPL is an example of a license like this.

Isn’t that called ‘copyleft’? I’m not sure ‘sticky’ is a common term.

Certainly not a term I've heard used to refer to licenses but it sounds less political than copyleft and I found it immediately understandable.
