Sip Leaves the Mac App Store
Olá Brothers Team (via Dan Counsell):
The App Store is a great platform for distributing software, but right now we need more control and freedom to build what we think is best for our users. Also, there are restrictions imposed by Mac App Store guidelines such as sandboxing that limit some of the features we want to bring to Sip.
In general, we believe that independently distributing Sip will allow us to deliver a better application and support to our users.
