You are absolutely right, $cientology is a dangerous cult.
However ...
This play is not endorsing $cientology. Instead, it is a not so subtle attack on $cientology using $cientology's own teachings against the cult.
$cientology is one of those scams that does not hold up well to rational examination. The more people know about the specifics of the scam, the less likely they are going to fall for it. Why do you think $cientology does everything it can to keep its "teachings" a secret, even from its own members? Until they have been sufficiently brinwashed, no rational person is going to believe they are infected with the souls of dead space aliens (a core $cientology belief). If the man or woman on the street knew about Space Tyrant Xemu from day one, instead of just taking a "personality test" do yo think they'd get many joiners?
From the "Playbill" quotes above, it remains difficult to conclude that the musical is attacking the Church of Scientology in any manner, subtle or otherwise.
Calling the musical "Unauthorized" does nothing other than give the impression that the Church of Scientology or any of their less obvious front groups would not approve. This tactic is also used by some book authors and the Church of Scientology itself to generate interest, and to cloak their involvement.
Here are a few links to lists of front groups for the Church of Scientology:

Too bad no one told Tom Cruise, John Travolta, Kelly Preston, Kirstie Alley or Giovanni Ribisi about Xenu, or Thetans, or how long it takes to get "cleared" before they spent over a hundred thousand dollars.
