Yeah, this does make the comparison less fair. Mozilla might have been similarly unhelpful about this issue.
But some other points still stand, like how Firefox got back to us quickly about the "delay", and how they showed our position in a queue. Google, on the other hand, was worse than just opaque about the process.
Why were we worried about Mozilla? Because things were so bad with Google that we figured something had to go wrong with Mozilla. So we put our psychological guard up just in case.
