This was written from my memory and it is likely that something might not be correct.
You see, Source Engine was previously GoldSRC, which was previously a work-in-progress version of Quake 2 Engine. Valve purchased the license for WIP Quake 2 Engine, which did not allow them to open-source the codebase. When developing Source Engine, Valve Software heavily modified the codebase, splitting the game and engine into separate folders. After Half-Life 2, Valve Software released Source SDK 2004, open-sourcing the code that wasn't from the licensed Quake 2 Engine. But before that, id Software open-sourced Quake/Quake 2 engines with GPL2 license, but its previous licensees had to contact them to get that GPL2 license on their codebase. It is 19th of February, 2025 and Valve Software still did not do anything to make their sources be available for open-sourcing. The main reason for that is because Source 2 was Source Engine, which was previously GoldSRC, which was previously a work-in-progress version of Quake 2 Engine. If they ask for GPL2 license, it is likely they have to open-source everything they based off from that WIP Quake 2 Engine they'd got, including Source 2! They wouldn't like to open-source Source 2, because:
- They can get some money from licensing it to others
- It is still in development, which i bet is already not a long time ago.
Well yes, but i'm not used to maintaining huge codebases. Maybe when i'll be an expert at Source SDK, then i'll try it. But you have to remember, that leaks are a gray area, and i'm honestly don't want to go there, even though i did before.
