I thought this was an interesting assessment of the exhaust over-run by Adrian Newey:

FIA F1 Media Centre (Thursday Press Conference said:
Q: (Edd Straw – Autosport) Adrian, there was a lot of talk in Spain about the legality of the exhaust-blown diffuser operating while the driver is off the throttle. What’s your interpretation of the legality of that, specifically relating to article 3.15 and could you explain your reasoning behind the position you take on this technology?
AN: Well, I think the key to 3.15 is that it talks about ‘driver over-run then the throttle should be closed’ then in brackets ‘idle speed’ so it seems to be implying that the throttle should be closed at idle, which it clearly is. What the throttle does on over-run at other times is not clear in the regulations, not as expected. Certainly, in the case of Renault, then they open the throttle to full open on the over-run for exhaust valve cooling, and that’s part of the reliability of the engine. It has been signed off through the years for dyno testing and for them to change that would be quite a big issue, because the engine’s not proven that it would be reliable if the throttle remained closed in that situation. Obviously if other people are going further and perhaps firing the engine on the over-run then clearly exhaust valve cooling is not part of that and that would be something that presumably they would need to explain to keep Charlie (Whiting, technical delegate) happy.

By "in the case of Renault," I presume he means Renault as an engine manufacturer/supplier, not Renault as a rival F1 team. He explains that the Renault engine uses the over-run to assist cooling. His car has a Renault engine so that's what it uses the exhaust over-run for. Fine. He then says, "if other people are going further and perhaps firing the engine on the over-run then clearly exhaust valve cooling is not part of that and that would be something that presumably they would need to explain..."

Doesn't that indicate that Red Bull (as opposed to "other people") are not using the over-run in a manner that the FIA wants reign in?

Or by "other people" does he mean "as opposed to Renault the engine manufacturer," including RBR and LGRP?
