Thank you

After 9 amazing years with Android, it's time to try something new.
I've moved over to Fuchsia (https://en.wikipedia.org/wiki/Google_Fuchsia)
where I'll be helping define security for a new, experimental operating
system.

My time in Android has been the most rewarding of my life. I couldn't
be more proud of our work in creating a trustworthy operating system
used by billions(!) of people, from rich to poor. It's quotes like this
which give me the warm fuzzies:

  "Android O is a big step forward," said Duo Security’s Lady.
  He said with O, Google closes the security gap on the iPhone.
  "It used to be if you cared about security you had to pay a
  premium and buy an iPhone. Soon, even a $50 Android device
  running O will be on par with a $1,000 iPhone X when it comes
  to security."

The platform team is in good hands, with Rene Mayrhofer now leading the
charge to make Android the most secure, privacy preserving operating
system in existence. And thank you to the rest of the team for making
my time in Android so wonderful.

And a special thank you to Stephen Smalley of the Trusted Systems
Research Group for his leadership and guidance. Android Security would
not be where it is today without you.

Keeping with the principle of least privilege, this change removes
myself from the OWNERS file for system/sepolicy. Let us always strive to
build systems so strong that we ourselves cannot even break into them,
and so private that people can trust us with their most sensitive data.

Test: Tested every day by billions of users. ;-)
