But there are other reasons to. Some married couples refer to themselves as we to an unnatural extent.
There are psycological differences in how people respond to groups vs. individuals. That's where "I vs. we" has relevance in ebay selling. Do you have more confidence in an individual or a corperation? Are you more likely to try and steal from an individual or corperation? If something was not to your liking to whom do you show more mercy? etc. etc.
Of course the higher-ups say 'I'. They are the ones who don't have to say 'yes' all of the time. 
Oh, like here on ebay? All the blues say 'we'. I asked once about that and it was ebay, not just the people on the chat team.
I like the part when you go to a car dealership and it is 'Team Edsel', or some such thing. You are talking to a person and they say that 'we' will see to it. You ask if that person is handling it and they say, 'no, the team is, or him, over there, or maybe that one, at the water cooler, will get to it first'.
We just LOVE these team events!
