The problem is that the whole scene has grown into a cottage industry of its own. As more and more "whistleblowers" come forward with extraordinary claims, it ups the ante for everyone else. To make the headlines (or to make serious money) you have to be more outrageous & more extraordinary than the rest of the pack. The problem is, that as more and more of these prove to be total bunkum, the whole alternative community get painted as whackos and crackpots, and eventually nobody at all - including die-hard devotees - believes anything that's said.... In effect, it blows itself out.
