To give some broader context to the request: There is a pretty rich tradition of popular Chrome extensions being sold to third party companies who leverage existing browser permissions to add in advertising or other junk. This is not a technical problem, it's a social problem. You cannot credibly commit to not selling the extension. Options within the extension don't solve the problem because the new owner can ignore them and rely on the browser level permissions. The only way to mitigate this problem before it happens is to ask for limited permissions, ensuring the new owner would need to request higher permissions should they engage in the problematic behaviour.
