Why there is no source code?

[ALIENQuake]

While in the ideal world, such things as a 'closed source' would not exist, this project needs to be closed for several reasons. The most important one is that there is a malicious actor in the Infinity Engine Modding community who has hijacked the previous mod manager and replaced mods with customized versions. This person promotes their own mods by recommending them over others and gatekeeps mods that interfere with their content.

However, you don't need source code to be open to trusting the application or contributing to it. If you are really interested in contributing and you are familiar with Windows Forms/WPF/c#/PowerShell, feel free to reach me.
