They are basically what is left of Nokia’s efforts with the N900 and N9 back in the day. But they chose a semi-closed source business model which severely limited community uptake and then seemingly got overwhelmed with maintaining their software-stack so now a lot of it is very outdated; which is why they are now slowly open-sourcing it, but it is probably too little and too late.

Edit: and their mix up with some Russian business (not sure about the current status of it) also doesn’t help instill confidence.
