You could argue that the license of the code, in this case AGPL, is irrelevant. I don’t think the source code is any easier to read than disassembled output.
As people in this and similar threads mention - it is easier to read; in fact, it is easier to read than even the preprocessed output, if you are familiar with the style and concepts.
Even though you don't understand this language/style, doesn't mean a user may not want to refer to source code, or someone may want to contribute to the project.
