GPL vs MIT vs Apache License – Understanding the Core Differences
When publishing or using open-source software, choosing the right license is not just a legal detail—it directly affects how your code can be used, modified, and redistributed.

1. The GNU General Public License (GPL)
The GNU General Public License was created by Richard Stallman as part of the GNU Project. It is the most well-known **copyleft license**.

* Ideal for projects that want to **guarantee openness forever**
* Not suitable if you want companies to integrate your code into proprietary software
