Another example that Honda and McLaren talk through media just like Red Bull and Renault. No joint press conferences, only delayed response to Boullier/Dennis (connected) by Arai,
http://www.grandprix.com/ns/ns31382.html :
[In response to public help offer] "We already work with McLaren Applied Technologies from the start of the project. They have developed software for our power unit, according to our requests. And they did a great job." When told, however, that the cooperation could be extended even further, he insisted: "We do not need help with technology issues. "Good advice, of course, is always welcome, but we do not need technology solutions (from elsewhere) for our project."
So why would McLaren management (Ron Dennis) start that since it's obviously counter-productive?
1. Publicity related to brand in light of bad results (same as RB)
2. Defending their own position (same as RB), different situation but Horner and co also pretended they didn't make any mistakes (they did).
Both connected to mistakes by said management like lack of big/title sponsor deal. If the reason was the price they can't expect anything better (on the contrary) with current performance, both in terms of amount of money and candidates.
3. Third reason (pure speculation) could be forcing personnel changes at Honda (that would be conveniently perceived as someone else taking the blame). Same as Red Bull - changes at Renault did happen (Cyril Abiteboul).
