They also deleted the official Facebook page, no trace of it left. I don't have any information either, but I suspect that they have been strong-armed into shutting down by the content industry. You know: "Disappear your software, or we'll sue you for millions." Not that they would've had a case, but enough money will always get the little guy to back down. A popular charge is "conspiracy", which basically means that there hasn't been an actual crime...

They used to communicate pretty openly and also respond quickly to support questions. I'm pretty sure they wouldn't have actively removed any trace of the software for anything other than legal reasons.

Let's hope the source code will accidentally leak somewhere...
