Mainly because Microsoft killed it off⦠(Score 2, Insightful)

Nokiaâ(TM)s Meego was absolutely a viable and innovative open source alternative, but a Microsoft lackey took over as CEO, wrote an idiotic memo about burning platforms, then abandoned it for the garbage barge that was Windows Phone. So, maybe look in a mirror. Jolla keeps the dream alive with Sailfish, but itâ(TM)s super niche. More mobile manufacturers should really provide it as a non-Google siphon alternative, but I doubt carriers have any appetite to push it through their channels.
