Very happy for you guys. But do take this as a shot across the bow, if and when it serves Google's agenda to shut you down they will. You have a great service, don't let Google control you and be beholden to them.
We have put all of our eggs in the iOS and Android basket. It looks like this year we’ll see a few Linux phone come to market... can’t come soon enough
I think you mean the N900, which I'd still be on if it did all the bands in my area. You're right though... probably the best Linux phone so far in terms of UI (I think the Ubuntu phone was too complex)
Ironically if they put the app on Huawei's AppGallery, it would have been up the whole time on a very non trivial amount of phones outside China where the AppGallery is preloaded before and after the Google ban.
