To quote my former self... won't happen. Hasn't happened for Maemo 4.1, won't happen to Maemo 5.0 mainly due to the proprietary drivers for the closed bits.

Scary part is making Microsoft aware that they have something that folks may actually want. They might lock it down even further. Or worse... add it to their ever-growing list of things that they have that they will find a way to exploit later.

Either way, it sucks. I disagree and would love to see it just put out there. Perhaps things have changed under Nadella than under Ballmer. It just cements the fact that Maemo was just never truly open. And I don't think that it will ever be fully open.
