Question

Linux is a good example of open-source software. People like the idea that open-source software is "free."

Is it really free? Why or why not?

Answer 1

Open source software:

Open source software is software with source code that anyone can inspect, modify, and enhance.

"Source code" is the part of software that most computer users don't ever see; which if the programmers access, can improve that program by adding features to it or fixing parts that don't always work correctly.

Examples: Linux, Firefox, Blender ....

Misconception that Open source is something free of charge:

Open source software programmers can charge money for the open source software they create or to which they contribute. But in some cases, because an open source license might require them to release their source code when they sell software to others, some programmers find that charging users money for software services and support (rather than for the software itself) is more lucrative. This way, their software remains free of charge, and they make money helping others install, use, and troubleshoot it.

While some open source software may be free of charge, skill in programming and troubleshooting open source software can be quite valuable. Many employers specifically seek to hire programmers with experience working on open source software

.Conclusion:

All Open source softwares are not free of charge. Only some are free, while there could be some other software programmers who could charge for the open source software they create.
