4. "Open source" used in marketing purposesJolla has used words "open", "openness" and "open source" in the marketing of their software. Wrong usage of "open source" during Jolla Tablet Indiegogo campaign was publicly notified by OSI. Few examples, latest known on top:
- 2016-02-24 Jolla at MWC16, Press Event, video at 0:11:05 -->
Antti Saarnio, Head of the Board at Jolla presented Sailfish OS to the press:
"We have Sailfish operating system, unique open innovation platform ...",
"Then, we have lots of interest from the security device vendors, who sees that our open source platform very interesting and very unique opportunity to start building on more security features on top of that." , and
"...open source is that when the core is visible, you can really see that there are no backdoors."

- 2015-01-29 TechCrunch (article) see also
- 2014-12-10 Forbes (article)
From the lists above we can clearly guess that the misuse of terminology is intentional and it's been going on for several years, despite the reaction of OSI. This misuse might have played a role in
- engaging the open source community to support SW development
- development of 3rd party applications running on Sailfish OS
- gathering contributions in the Jolla Tablet Indiegogo campaign
5. The future of Sailfish OS open source licensingAccording to Antti Saarnio, Chairman of the Board at Jolla in an interview to TechCrunch on May 28, 2015:
"We have a timeline to open source basically all of the non-commercial parts, some of them are third party parts which we can’t open source of course. But we have a timeline to open source most of the platform — because it helps us to work with the developer community and also our partners. But we are not yet releasing the timeline. We will come out very soon with an announcement about the scale of this open sourcing schedule."The promised announcement has not seen the daylight by now (February 2016), but instead the "open source" was once again mentioned as an existing feature of Sailfish OS by Antti Saarnio during Jolla's press event at Mobile World Congress 2016, according to our anonymous source.
