I had been Sailfish user from day 1 (i.e. Nov 2013). Started because of privacy and Linux, but stayed also because of UI. I even bought 2 licences that I never flashed to real devices (because of different reasons).
However standard upgrade (from UI) couple of months ago failed totally and that last phone is now unusable. I did not see any reason to reflash the old hardware, but descriptions in this forum show, that new one I had pre-bought as the follow-up (Xperia 10 V) is not at all usable in full functionality and I did not want to buy C2 as another follow-up.
It is so easy to turn a user to Android. Of course I choose 100% degooglified one, but Android it is. In the first weeks I thought, that it is temporary and Xperia 10 V will be soon fully usable, but it still isn’t. From that standpoint Sailfish looks like a train that is pulling away from me.
Words about community and cooperation are nice, but at the end of the day you need a working phone on modern hardware, that you do not need to plug into power outlet twice a day.
Of course I understand that developing Sailfish is always an uphill battle and it is very good that this alternative mobile OS exists (big thanks to everyone involved in the background). But facts of life may very easily turn users away and then the question is, if and when you can return.
