My statement is probably phrased wrong, but it still stands. The GNU toolchain hasn’t been made open source overnight to answer a management problem. There’s a whole point to the GNU project besides “hey, we don’t have enough resources, let’s make it open source”, there’s a whole philosophy behind it. The tools it created did help development for other stuff, but GNU development hasn’t been the easiest task, just look at GNU Hurd for example.
Also, there’s a distinction to be made, my comment didn’t address open source tools, it’s about implementing open source practices inside development, which is two very different things.
What do we know exactly ? Except that the deadline has been estimated wrong and that they’re working on it ?
Those are two different things. While open source development has been successful it’s not adapted to every situation.
Also, “open source community” isn’t a thing. There are open source communities formed around specific software but forming such communities takes time, and they’re usually not as big as you might think. What makes those communities happen is that the software they’re developing helps a lot of people in their work. Wether you like it or not, OB’s user base is pretty niche and I doubt any developper would be intereseted to work on it in their spare time while not being paid.
