Jeezus, I never claimed anything about the McLaren press release other than to say it was an official press release - I'm not even sure I said that much, go back and check yourself if you're not too lazy.
Mercedes can't just quit a partnership unilaterally. They had to get McLaren to agree, so they had to give them something in return - a sweet guaranteed deal on engines, for example. End of.
As for the bait - sorry, "lies" - you list - I'll spare us all the argument over those, and instead just point out that Mercedes owned precisely 40% of them. I see no reason to trust Mercedes over McLaren, or vice versa. But I'm not even saying that Merc lied. I'm not even saying that they misworded their press release. The fact that both press releases can be true at once doesn't seem to sink in with you.
It seems that your argument -whatever it is, I still don't know - hinges on your opinion that McLaren are not just liars, but so compulsively so that they can't possibly write a true word. Face it, your argument is entirely based on the fact that you don't want them to have a guaranteed engine supply. It's a bit worrisome, your hatred of the team. Unhealthy.
And the fact that you started posting numbered rebuttals accusing people and corporations of lying concerning one single word in a year old press release, after only two posts is...weird.
