Honestly, I think you are being naive about the motivation of the schoolyard bullies. That attacks on Elon have been, from day one the bullies entered the school, very pointed, coordinated, and relentless. You believe the bullies have, at some level, good intentions. I believe most of their intensions are purely financial self interest. Talk is a waste of time, it would be just political posturing by all sides - and the bullies will not change their mind, as their pockets are not filled by Elon, but by companies and interests that are threatened by Elon. Elon tried something like you suggested, like agreeing to interviews from NY Times, having a dedicated pr department to combat the FUD - all produced nothing good. Because the interests are different - if he paid the articles, like everybody else does, then the coverage would be positive - but also ineffective/just another useless GM style fluff piece.
And in fact by going his way, ignoring the media, the media attacks have become less and less effective, and lately in fact some of the Media realizes that good stories about Elon are good for them too - it differentiates them from the crowd in a good way - hence the Time etc person of the year.
I suspect pretty soon something similar will also happen with the schoolyard bullies - sooner or later they will come to Elon, groveling for positive attention.
