Of course, this sort of thing is basically impossible to disprove - especially without source.

If I were looking for a well-hidden backdoor, I wouldn't bother with source. There's no guarantee that a particular binary was produced by a particular group of source unless you can compile it yourself to the same set of bytes. Even then, you've got no guarantee the backdoor isn't introduced as part of the build process or a compiler quirk, rather than being in the source.

As for proof in this particular case, I find the claim rather extraordinary, so I would place the burden of proof on the claimer. Let's see an exploit.
