That's because their message is inconsistent and contradictory. They've only themselves to blame when people try to join the dots and find the only solution that produces logic they recognise is to add some dots of their own . If you want people to trust you, don't go around giving different stories to different folk and changing your position.
Nonsense. Intelligent human beings are expected to connect dots that represent established facts or well established conclusions. When you start assuming the FUD spreaders are the only ppl telling the truth (against all reasonable evidence), the cognitive dissonance involved in such mental gymnastics isn't to be blamed on bad PR messaging.
Also, a note on the theories involving allocation strategies...consider the possibility that MS would anticipate PS4 to sell out in a given region. In that event, it serves MS well to have units on shelves in those regions and to make the retail presence strong enough to be capable of capitalizing on the lack of PS4's. Maybe they wanna make sure they can keep strong stock in places where they think PS4 won't be available.
