Comment 3 for bug 1564209

For click packages we compare consumer_key == reviewer_username. It seems the old API however returns LP usernames for some people, which of course won't match the consumer_key.

If we could change the old API on the server to also always return consumer_key in the reviewer_username field, then the gnome-software plug-in could use this same tactic. The only major concern here is if it will break software-center for 14.04 users.
