Say I work on a software project where I want to publish the source code (for example on GitHub) solely for review (= access, analyse, test and otherwise review the code as a reference). Now, I asked here because I am aware that software like that is not considered "open source". Some companies have licenses for that.
Microsoft has the MS-RSL License
Mega, for instance, has the "MEGA LIMITED CODE REVIEW LICENCE"
Now my question is, am I allowed to use one of those licenses as well and change the content to fit my project? Or are those licenses licensed exclusively to the company which issued them?
