Google had problems with getting updates out to devices
And with just a little bit of developer money, so many devices out there could be running a safe, secure version of Android instead of being merely abandoned and left vulnerable ("you luddites running six-month-old phones...").
I've been waiting to see a nonprofit that would sponsor such work and then sell decent smartphones to people who could use them to benefit themselves economically. People throw away ("recycle") perfectly good hardware because the software is too dated.
Oh, I know, "that dual core phone from last year with only half a gig of RAM just can't do anything useful...."
