As far as I can discern, between a couple different sites...
There was an announcement of an upcoming story on a discovery of a communicator on Trek Prop Zone where some of the HeroCom founders are members and as such it was to be a "benefit of membership" to hear about it before the story actually released on Friday. Someone from TPZ went to HC and phished a directory uncovering a set of images that were ready for the story release but had not been posted anywhere. One or two of the pictures were posted at ASAP and here. HC's owners were notified of the premature release of the images and they asked that they be removed until the story is published on their site on Friday.
No cover up, no smoke and mirrors, no "Com Mafia", no one trying to withhold information, just a fan site that wanted to release a story about a possibly unknown Trek prop and someone stole their thunder. :unsure
Simple as that.
