GPL is viral and imposes restriction which you can't foresee. A recent example is the AppStore fiasco VLC had. It required a complete rewrite and additional development years to get it in the store just because the original code was GPL. Please think twice before using (A)GPL and make sure you have checked all consequences.

GPL is indeed viral, however it's viral under certain circumstances, not all. AGPL changes some of those circumstances.

I do not believe that _running_ your software on top of AGPL-licensed Juju makes one iota of difference.

The App Store is different: the restrictions the App store adds are at odds with GPL's defined freedoms. Not the same issue here.

Everything you program that uses Juju's API, automatically also gets AGPL licensed and that's a big no-go for any commercial development.
