The only reason those phones are getting adopted at all is because Nokia pumped out a ton of low spec budget phones to try to gain some traction in the mobile device industry in places and demographs where Android and Apple aren't
That seems like a pretty smart business decision. No? Also, Nokia is a very trusted name in many non US markets.
. As soon as more phones like the Moto G hit those same places, you'll see the same thing that has already happened in the high end phone market. People will see one phone with a limited ecosystem and another that isn't and make the obvious choice.
I remains to be seen what happens to Motorola. It could just be another Google experiment that goes away.
Frankly I have little to no faith in a company that took 3 total OS refreshes (Win Mobile, WP7, and WP8) just to now start catching up to features that Android and iOS users have taken for granted for over 2 years. Like how just getting notification centers and separate volume controls in 2014 is supposed to be big news is awful. MS is still stuck on the slow update cycle they've always operated under for years with Windows desktop OS and they needed to break that mentality years ago.
I remember when the same thing was said about Apple. In the mid and late 90s they were low in cash and going to close any day. Friends had stock options with a strike price of $30 when the stock was trading at $15. When you went to the corporate HQ at 1 Infinity Loop the parking lot was half empty. Seemed like there were more people at the Computer Literacy Bookstore that shared the parking lot.
But, who MS picks as a new CEO will be telling. My hope is for someone like Elon Musk, but I think he is having too much fun with Tesla and Space-X.
