Honestly i can't indeed blame jolla for not opensourcing it. they decided to go for a big risk and they are and never be forced to open something in wich they spent money and efforts. Only thing is that they made a mistake when they promised it, two years ago. I can forget it, i think they really were sincere, but investors didnt agree with them. However that was a lack of sense of responsibility.

By the way, stop to talk about it, i am still waiting for a reply:

Why devs and people involved in porting sfos and other important project like that, are not really involved in nemo mobile?
i am not a coder, i am not an expert so correct me if i am wrong, but it runs with same components of sailfish. why there is no so much interest about it? reading comments on this forum i expected that it would have gained much more interest than sailfish...
