An open source license protects contributors and users. Businesses and savvy developers won’t touch a project without this protection.
Use the license preferred by the community you’re contributing to or depending on. Your project will fit right in.
If you have a dependency that doesn't have a license, ask its maintainers to add a license.
The MIT License is short and to the point. It lets people do almost anything they want with your project, including to make and distribute closed source versions.

The GNU GPLv3 also lets people do almost anything they want with your project, except to distribute closed source versions.
