Why is it that open source software is so popular?
assistant
Open source software is popular because it is free. It is free to use, modify, and distribute. This means that anyone can use it, and it is not owned by a single company. Open source software is also popular because it is reliable. It is developed by a large community of developers, and it is tested by many people. This means that it is more likely to be bug-free and secure.
