I noticed this too, and immediately thought of the FSF. But I kept reading and thought this was different:
> Note, you don’t grant these rights to the AMP Project, you grant them to Google. Google owns the code and patents.
> Note, you don’t grant these rights to the AMP Project, you grant them to Google. Google owns the code and patents.
On the other hand, in AMP's case the CLA allows Google to start distributing the software under a proprietary license in the future, if they so desire.
One example of this difference was the time when Gitlab stopped requiring a CLA, after being prompted to do so by the Debian project: https://about.gitlab.com/2017/11/01/gitlab-switches-to-dco-l...
