Mozilla Public License v2.0
practical callout
MPL-2.0 sits between permissive (MIT) and strong copyleft (GPL). You can build a proprietary product that includes MPL-licensed files, but any changes you make to those specific files must be published under MPL. The file-level boundary makes it friendly for mixed codebases.

network deployment note
No network-deployment obligations. MPL-2.0 is a weak copyleft: modifications to MPL-licensed files must be shared under MPL, but you can combine them with proprietary code in a larger work.
