Random insight for the world: shipping the license for your software with your software is required and also good project hygiene.

A project that claims a license but doesn't include its terms is ambiguous.

Despite what you may think, just saying "hurr durr im MPL" (or Apache or whatever) isn't enough. If the software is non-interactive, you need the license shipped so it can be read by the consumer separately. If the software is interactive, it needs to be exposed *somewhere* in the app too!
