It seems rather silly of them to link their new currency with the Church of Scientology that way - whether or not they are in fact Scientologists.

While theoretically it shouldn't matter who initiated things so long as the code is open source and scrutinized by many - I think 'an anonymous Japanese/English cryptographer 'is a heck of a lot of a better start from a PR perspective than 'Scientologist Investors'

Even the name 'StealthCoin' seems to make little business sense.   
Bitcoin is already burdened by some perceptions that it's too risky, shadowy and not for 'legitimate' business - why would someone genuinely wanting an investment return push further in that direction?
