You raise an interesting point.  Moderate Muslims and even those who have left the religion are silenced by media outlets who could otherwise give them an excellent springboard for much-needed discussion.  Both Maajid Nawaz, founder of Quillam International, and Ayan Hirsi Ali are listed as anti-Muslim extremists by the Southern Poverty Law Centre in the US.  Tarek Fatah is seen as a right-wing extremist. Even if Muslims and ex-Muslims wish to speak out it seems they are silenced in the ever-widening circle of don't ask...don't tell...atmosphere surrounding extremism.  Khan would better serve her religion if she were to unequivocally condemn such acts, with no ifs, ands, or buts.  I think people like Khan are part of the problem, her M103 at the centre of it.   It's not that such  moderate views won't make for interesting press, it simply doesn't seem to fit the current narrative: one that seems to want to force how people think.
