I have asked. I am still waiting to get it.
There seems to be a lot of reluctance regarding access to the Matrix code.
It’s either open or it’s not.
The phrase open source usually refers to a community developed and community supported hardware or software project. Typically, the phrase open source means that the technology is free to use, free to share and free to modify.
Matrix so far feels more like closed source as it seems to be exclusive to a team, we need to pay a license to gain access to an account manager to get granted special access to look at the code.
Some software has source code that only the person, team, or organization who created it—and maintains exclusive control over it—can modify. People call this kind of software “proprietary” or “closed source” software.
