I have seen some hypotheses that the recent series corporate actions and statements are a sign of SO/SE being in the process of being, or about to be, sold. Arguments cited include the corp statements being made in paywalled areas and addressed to an audience that seems very distinct from the community, the choice of CEO, the push for a 'service sector' flavour of tensely smiling hospitality, and surely some more I can't recall in a coherent form. 

Just how plausible and implausible, and how founded or unfounded, is such a hypothesis? Is it, as far as people more knowledgeable either about business in general or about the specific case of SE/SO, strategically consistent or even outright connected with the corp's behaviour (and a likely cause thereof)?
