Some component which are indispensable are closed source and proprietary. The day Jolla Oy will terminate its business, those components could be probably lost forever and whatever you can say about - I do not see around anyone that can write them from scratch also because none apart the Jolla employees and ex-employees have any kind of knowledge about their internals. Therefore the saga will last few years after the Jolla Oy mobile devices business termination, in the best case.
Some people did a porting to not officially supported devices but also those porting contains the same proprietary closed source stuff. Is it right?
NEWS UPDATE
My Sony Xperia 10 II arrived on 26th May 2023. On 26th June, I proposed myself like a product manager with the aim to refactoring SFOS in order move forward toward a better new generation of SFOS (code-name RedFish OS):
- more open
- more stable
- more independent
- better hardware support
Which seems a too-big-too-achieve promise but considering that at the moment - the community, at least - lacks of basic tools and skills about embedded system, the receipt is quite straightforward:
-
lack of basic tools → huge bottlenecks, once we have the tools the bottlenecks are out of the scene and we can start focusing on the lack of embedded systems skills
-
lack of skills → in part this gap depends on the lack of proper tools, therefore it can be fulfill quite easily and in part tutorials and mini-courses could develop the skills
Giving to every aspect 1/N of weight - flat hypotheses - it is possible to address properly 3/4 of those gaps in a reasonable time. Then, it is supposed that things will start to happen by themselves faster and faster.
