If they are "The most trusted WordPress platform", that implies there is more than one platform. That implies that none of them are first party WordPress. So I don't buy that.
(Regarding their plans, I think they would be safer to put the word 'Plan' at the end of their plan names.)
I know what you mean but if CNET Downloads advertised themselves as “The Most Trusted Source for Firefox” The Mozilla Foundation/Corporation would not allow this. A consumer new to the term WordPress might be given the impression that wpengine.com is a more trusted platform/source for the software than wordpress.org itself.
