Well, some of the people who are/were a little more involved with the GiFT project (e.g. J. Ashton) already stated on Slyck that they could prove this is a lie - and I tend to believe them.
That aside there were announcements from Razorpop - while they were working on TrustyFiles 2.2 - that it would be open-source like the GPL required it to be. A few weeks later they release their client and state the code in this version is all theirs they just rewrote a couple of thousand lines of code. - Really, you don't cough up a Gnutella implementation just like that.

I wish someone from the FSF or so would offer some money to sue those Razorpop people because ripping of OS technology is not a respectable business modell and people should be warned not to use TrustyFiles. You can have the same features from people who don't steal other people's work (like BearShare, LimeWire or even Shareaza).
