"Complete change" is IMO something else than just "open source the damn thing." I was expecting some deeper technical flaws that should be addressed in that "complete change" (hinting that just about everything with Sailfish OS is wrong and bad) instead of yet another punchline that in itself doesn't really mean much. Open sourcing is and has never been a magic bullet to correct it all (if it did, there wouldn't be open source projects consisting of pretty awful code and/or technical choices) and it is known fact that if platform is dying, open sourcing never turns it around. IMO the suggested dual/tri-way licensing scheme in similar vein to Qt licensing would be a good way to go, but also investors need to be convinced of it.

As Sailfish is based on already open source code for quite big part, issues lie mostly elsewhere. That can be debated, but please, don't offer empty slogans as a solution to real or imaginary need of "complete change" in platform.
