Open Source Misconceptions
Even in linux and Open Source spaces, misconceptions about what "Open Source" actually means are widespread. Since Open Source already has a documented specific definition describing what it IS, below you'll find a list of things Open Source is NOT:
1. Open Source does NOT just mean source code access
Aside from being the first sentence of the Open Source Definition, this statement captures the most common misconception about Open Source. While the Open Source Definition does require source code access, this is one of many necessary components. Source code access alone is not sufficient. Software that provides source code access but does not meet other Open Source criteria falls into the category of source-available software.
2. Open Source does NOT mean zero-price
While many Open Source software projects are provided at zero price to users, there is nothing in the Open Source Definition that requires this. On the contrary, the Open Source Definition explicitly REQUIRES that selling the software be permitted:
The license shall not restrict any party from selling or giving away the software
There are numerous companies that make tremendous amounts of money selling Open Source software. As long as the license for the software complies with the Open Source Definition, including but not limited to providing the source code to the customer, that software they're selling is Open Source.
3. Open Source does NOT mean no copyright
Copyright is the legal framework by which ownership is conveyed to written works. Open Source licenses, like any other licenses, are a way that software writers can provide access to software they have copyright to under a specific set of terms. So not only does Open Source not mean no copyright, it explicitly depends on copyright. Without copyright, there would be no way to legally enforce licenses like the GNU GPL. For example, without copyright, companies who violate the GPL wouldn't be violating any legally enforceable right, and so they couldn't be legally held accountable
4. Open Source does NOT mean whatever you want it to mean
The Open Source Initiative maintains trademarked symbols tied to the Open Source Definition. It is an industry standard term with a specific meaning. It's critical that this term's protected status be respected, to prevent abuse and fraud by companies who would like to mislead their users into thinking their software gives them certain rights that it does not. Please do your part by not perpetuating any of the above myths, in an effort to prevent false advertising and fraud.
