Vic Gundotra from Google -keynote at I/O 2010:

If Google didn’t act, it faced a draconian future where one man, one phone, one carrier were our choice. That’s a future we don’t want. […]

So if you believe in openness, if you believe in choice, if you believe in innovation from everyone, then welcome to Android.

Businessweek today:

From now on, companies hoping to receive early access to Google’s most up-to-date software will need approval of their plans. And they will seek that approval from Andy Rubin, the head of Google’s Android group.

We created Android in response to our own experiences launching mobile apps. We wanted to make sure that there was no central point of failure, so that no industry player can restrict or control the innovations of any other.
