Nah, there has been some extremely poor decision making and execution at Jolla. Blaming the market is ridiculous.

Whilst 3rd party Android ROMs have exploded in popularity, FirefoxOS has carved a decent niche and continues to expand, and UbuntuTouch already has 3 devices on the market despite effectively still being an early beta, and they already have 3rd parties willing to base their ROM on UT (KDE Plasma). Meanwhile, after 4 years, and coming from a very solid base with Maemo and Meego, Sailfish has seen meagre progress and Jolla finally have a small 3rd tier Indian brand that specialises in the ultra budget market (one not ideal for SF given its massive resource issues). Also, there's some reason to be sceptical given that they could only show a Jolla in plastic casing 5 weeks ago, but supposedly an all new device will be available in October ... plus they specialise in MTK phones (no SF adaptions yet) and since almost all their phones are off the shelf from chinese and taiwanese OEMs, they likely have little to no experience with hardware adaption and support.
