Not allowed. But maybe someone will ignore the strange licence and send you a private message with a link. The problem is the licence is pretty hard to understand. I’m not even sure if it is forbidden. But there is a discussion about that elsewhere if you search for it.
Update, Links:
I guess these lines are important: “Fairphone grants you (…) non-transferable, limited copyright license to download, install and use the Software for non commercial purposes only on a Fairphone 2 device in machine-readable (i.e., object code) environment”, “You must not take any actions that may result in the fragmentation of Android.” and “You are also not allowed to remove portions of the Software, alter or otherwise modify it, or translate, reproduce, copy, reverse engineer, reverse compile, disassemble or transfer the Software.” But I don’t see a lot about sharing here and the non-transferable is pretty vague. If everyone can download it you are practically sharing it anyway, it just makes things difficult.
But I’m not a lawyer and I guess the same is true for @keesj. There is no lawyer-like official statement yet, I think.
