They switched to iOS and Android from what existed prior - mostly Symbian, BlackBerry and Windows Mobile. This new cycle that the majority is in currently is bound to wind down too. Then what?
The part about less itches to scratch... man, tell me about it. I think it's an isolation tactic that's counterproductive in terms of having native apps or rarely seen/used apps because it's not popular here but overlooking the popularity elsewhere.
And by "friggin' miracle", you mean money, right? Money (and marketshare) will deliver a native app. Folks not using Android could be a blessing - they'll end up writing native apps that take advantage of the UI only if they think it'll be well-received, well-used and they can make money and/or grab marketshare they've been shut out of before.
Sadly, the way that anything popular is shunned here, say goodbye to native Instagram, Skype, Vine and a few others because well... nobody here would use it, the market that owns a Jolla phone also would rather use Diaspora, Tox.im, and something else (lord I forgot the name of that pic sharing web app, M-something).
If Whatsapp was there on day one, we'd complain about it then too. It's closed source, it's not secure, it's not interfaced by terminal... I can continue.
