The Desteni logic reply to that would be that your very limited with-in your own observation.
You 'will never' allow yourself to reach out.
They probably would say something like that, but it may be they don't all acknowledge Poolman's role in their group. They perhaps see Desteni as an experimental "interdimensional" exploration amongst equals and/or a political campaign.
The first wave of followers were attracted by Sunette Spies' "Look at me, I am a portal" act while Poolman remained behind the scenes. He is now more prominent but still hiding. Followers are now being drawn in by the "equal money" scam, not so much on the strength of Poolman's ravings.
However, the more he enters the spotlight, the more Desteni loses any credibility it could possibly have. Poolman is completely ineffectual as a public speaker. If he allows himself to be filmed, as he's suggested will happen, it is likely to amplify the incompetence of his presentations, which are at best comedy routines.
Training would not rectify that problem because Poolman does not convey that he has the basic level of aptitude required in the first place. Sunette Spies might have had potential as a public speaker, but since they "closed the portal" she's lost it. Her recent talks are boring in the extreme, which suggests she has had the reins put on her to stop her from developing her act of her own accord.
Poolman placed Spies in the position he did and gets other followers to promote Desteni in order to compensate for his own lack of skill. It is only by continuing to employ substitutes for its leader that Desteni can progress, but that means Poolman risks losing power.
The whole concept is very flimsy. A girl who pretends to be famous dead people on YouTube, a fake internet-based political campaign and a guy who doesn't have a clue how to present himself and is incapable of making any coherent statement are not good strategies.
What they need is at least one book available in most new age bookstores, an oddly charismatic or hypnotic speaker who goes on lecture tours, centers of activity established in major cities and a philosophy that taps into the zeitgeist, no matter how crap it is. Something like Eckhart Tolle or Andrew Cohen's schemes.
Desteni however is an inward-looking, mainly internet-based obscure sect with one relatively remote compound, a shy maniacal leader, an apocalyptic, totalitarian vision and a do or die mentality. Does not bode well.
