Godot is licensed as an "open source" project. That means the code that runs it is available for literally everyone to look at. Users are permitted to make changes to suit their needs and they have the option of asking the maintainers to consider adding those changes to the core project (through a pull request).

The advantage of this is that Godot can potentially get updates for close to free from talent from around the world, gradually improving based upon the dedication of people that just care about the project.

The downside is what you see here, stupid people thinking they are being helpful by having a computer spit out unverified, unorganized crap that the maintainers still have to look at to determine if it's worth going into the project.
