When you distribute, you are responsible for ensuring your customers get
the source *you* used.  It's almost impossible to ensure that somebody
else's git repo carries what *you* are responsible for, and you would be
hijacking their bandwidth and server space for *your* project.  That is
often tolerated if your project is also completely open source, but is
certainly frowned upon if you are a commercial operation.

If you zip up the source and include it in your CD or download every
time you publish, you have fulfilled that requirement without stepping
on any toes.
