Users need to have greater control over the data their extensions can access...
Are you sure you meant 'users' and not 'Google'?
They're going to limit the ability of the addon APIs to do what the users want the addon to do, and that's the same as the user having greater control, apparently.
Why stop there? Why not give the user total control over the data their extensions can access, and just get rid of extensions completely? Since the user having control means limiting the kinds of addons the user can choose, of course.
