Basically described how every corp/alliance operates in eve online. Some are just better at deceiving their members even to their benefit or even themselves as leaders/representatives of their own corp/alliance. In most cases it is more honest and beneficial to be lied too rather than follow someone delusional about what they are doing.
At the end of the day it is about the needs of the many, the corp/alliance represent the many, the individual member is just a singular pawn who even if benefiting from being a part of the corp/alliance is ultimately serving it’s goals and not just their own.
So you can say blah blah blah your scamming players. To the leadership of a big alliance they are just accomplishing goals in an efficient manner and protecting their wider organization from the interests of the bottom feeders who shouldn’t be responsible for making leadership decisions.
They are new players who will come and go and have no real responsibilities or attachments, in some cases they are likely just spies. So deception is just part of the game to both motivate players to cooperate with one another to achieve goals for both the many and the few but also protect themselves from potential threats from within.
Unfortunately democracy doesn’t work in the chain of command ideas have to trickle down not up from the bottom. They can do things to serve their members under them but ultimately only to help motivate efforts to the goals of the organization as directed by it’s leadership.
Sounds like this guy could just be practicing to become a leader of his own alliance.
Eve online is a very complicated game.
