While I can agree that if you want to make a device with mass appeal you probably should focus your efforts, this doesn't seem to be happening. As far as I can tell Pine does not put any significant effort into the software, but instead hopes that the community will do it. Now if you rely on the community, focusing only on a minority (manjaro users) of a minority (Linux mobile developers) of a minority (phone users wanting a Linux phone) might be a bit too much focus I'd argue.
