How might the open source system of sharing and developing software serve as a productive model compared to proprietary forms of commercial software development?

I have summarised a few points that describes why open source system of sharing would be a productive model as compared to proprietary softwares.

Business users can take a piece of open source software and tweak it to suit their needs. Since the code is open, it’s simply a matter of modifying it to add the functionality they want.

Open source software is generally free, and so is a world of support through the vibrant communities surrounding each piece of software. Linux, for instance, has an online community with excellent documentation, forums, mailing lists, forges, wikis, newsgroups and even live support chat.

In open source system, there are countless developers and users working to improve the security of open source software, so there are just as many innovating new features and enhancements to those products.In general, I feel that open source software gets closest to what users want because those users can have a hand in making it so.

Lastly, it costs you nothing to try out before buying.

From what i gather from this article, I think that technical superiority is typically the primary reason enterprises choose open source software.Along with those benefits that I listed out, I believe that open source system may serve as a productive model as compared to proprietary softwares.
