Point is, none of the provided examples are completely FOSS but contain more or less significant pieces of closed source components, proving my original point that there are at the time (at least almost) nobody in consumer product business doing everything completely Open Source. Sailfish is mostly, open parts are:

- Mer Core
- Nemo middleware
- Most core apps

These are the parts that make up most of Sailsifh OS and by statement by Stskeeps: "default policy is to open source unless it's covered - and we usually contribute those to Mer or Nemo Mobile projects." Which IMO is pretty clear. But obviously not enough for some until every single piece of it is Open Source.

Closed parts are:

- Sailfish UI, which is the part Jolla wants to license to other manufacturers to generate income and which also contains some licensing agreements that prevent Open Sourcing it completely.
- Hardware adaptation, which they simply cannot Open Source as it contains proprietary stuff owned by others.

But for now, enough offtopic. Maybe this discussion could continue in some other thread...
