This is because you cannot use open sourcing to save dying platform. Open source should be there from the beginning and it needs robust community behind it, which requires some good faith instead of cynical infighting and clinging on to every single mistake/wrong/annoyance possible. Which is why I'm currently very skeptical if open sourcing would make any difference with Sailfish. Another point of view is that open sourcing closed bits is something more than just changing labels in some papers. You need to know exactly what you are open sourcing, you need to be 100% sure there are nothing infringing other licenses and doing that research does cost time and at times money. Do it wrong and you end up in court and bankruptcy. On top of that, you need to have a way to organize everything related to that code, contributions, feedback etc etc. or whole open sourcing will result in utter failure and more "they cannot even do that right"-comments here and abroad. Still, they promised to open source many things and I do believe they will do it. Patience is a virtue.
