TWTR is a largeish company. I have no evidence but presume it is overwhelmingly likely that their scale a) makes getting inside the head of every employee is impossible and b) fosters the right conditions for a healthy number of little agenda-ized splinter cells with various passionate motivations and whatnot.

Besides public state and company size, Twitter is also new media. And all media is information warfare. (Hmm, that sounds a bit strong, especially considering the toxicity that is the platform itself; I mean the term generically speaking.)
