A large number of open source projects you find today are GPL Licensed. While the GPL has its time and place, it should most certainly not be your go-to license for your next open source project.
A project that is released as GPL cannot be used in any commercial product without the product itself also being offered as open source.
The MIT, BSD, ISC, and Apache2 licenses are great alternatives to the GPL that allow your open-source software to be used freely in proprietary, closed-source software.
libstorages is released under terms of Apache2 License.
