Tizen is reputedly of bad code quality, especially security-wise.
Sailfish is still out there as Jolla scraps away.
It’s a pity, as those projects did attract some powerful backers, who just weren’t very committed to them.
> The OS is an evolved continuation of the Linux MeeGo OS previously developed by alliance of Nokia and Intel which itself relies on combined Maemo and Moblin.

Ridiculous series of merges and forks.
Sailfish's market share is so low it doesn't seem to be measurable.
When these projects were at their peak there was just about a way for them into the market. There isn't now. If they spent their time working on just one branding of these projects instead of creating yet another new name, website, and icon they might have gotten somewhere.
Those projects were a bizarre affair. There was I think Maemo, Moblin, LImo, SLP, Bada, Leste, MeeGo, Mer, Tizen, Sailfish, Nemo... all forks, merges, reforks of the same thing. They seemed to spend all their time and energy continually rebranding, forming and disbanding consortiums, creating new websites and logos. They never just got on with it. Ridiculous wasted effort when the market was possibly still just about open to them.
