The default value is true. In most situations you'll want to zip source files. Having access to source files is especially useful when you want to diff particular changes in code. However zipping source files consumes a bit of CPU at analysis time and a bit of hard drive space to keep the zip files for each analysis result. So it might make sense to prefer no zipping source files.
