No, an extra restriction ("For open-source use") is added on top of the GPLv3 license, which violates the license, actually (see §7):
> All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term.
It's better to license under the stricter AGPLv3 and not put any extra conditions.
