If you don’t have a license to use a software product, you face the risk of litigation and project take-downs. Notably, the law attaches copyright to a software developer’s code by default. Keep this in mind when you come across software that seemingly has no license. Moreover, when an Open Source code doesn’t have a software license, don’t feign ignorance. The owner of the source code still reserves all its rights, so you can’t copy, change, use, or share it. When you use this sort of source code, attribute the owner to your project and recognize individuals who supported it as contributors.
