Not negative, but concerned. In short Stskeeps said that now things are closed, and future is unknown, but it's not easy to make things open. If you want, make a formal inquiry to Jolla about opening things. Did I sum it up right? You can assume a few things (but again, these are just assumptions): 1. At the release core applications and UI will remain closed. 2. Jolla is undecided yet about future. Why I find it concerning: 1. No sharing of effort with Nemo about UI and applications. Ideally I'd even prefer Nemo and Sailfish to merge into one. Or Nemo to become what Fedora is for RHEL (note all of them are open). With Sailfish being closed - it's impossible. 2. Harmattan pitfalls risk. 3. Disadvantage in comparison to fully open systems (Firefox OS). I'm not trying to be negative, I'm trying to analyze the issue objectively.
