I've been giving this lots of thought recently, with all the changes to Android. I frankly don't really care all that much about the politics behind open/closed software. It's almost never been a deciding factor for me and I've been bit and blessed about as many times by stuff from either camp. I also know that right now and in the near future, if Google completely closed source Android today, it wouldn't impact me in the slightest because there's really only two viable mobile OSs at the moment, neither of which I spend any time mucking around with the source on -- and neither of them are built by Mozilla.

I think what I care more about is accessibility. How easy is it for me to build stuff on their platform? Google makes it really easy, Apple makes it really easy. There's a healthy debate as to who makes it easier, but in the end it's not about openness it's about accessibility. If Google replaced their kernel with the most locked down closed source kernel ever conceived tomorrow, but made no other changes, it wouldn't impact that in any way.

And that's what I, and to be honest most developers care about, getting stuff done, which is what accessibility is all about.
