Only thing with trying to force the hand that feeds, is they might get a little irritated at being made to look like fools and Rossi may well find himself out of a contract next year. Not that he would care, he's got the accomplishments to go with this career, so really I don't think he'd be all that bothered by it. Especially if he has to ride another turd for the next two years.
This could be the first shot across the bow from Rossi. Basically telling Yamaha fix this POS or I walk.
I myself don't like seeing this stuff happen because it means that things are starting to sour from within, and that's never a good thing. If a team constantly battles and you can see them doing their best. Then that at least says they are working towards the future with solutions. But when you get a rider and team starting to just give up, then it tells me there is more going on behind the scenes. Which is why I think right now, someone(or several people, Rossi included) are getting their butts chewed for all this.
