This claim makes limited sense.
They say that the volume of content was too large. If this was actual chat (text) then surely a combination of traffic analysis and keyword / text analysis is actually reasonably easy to scale? Perhaps it's all streamed audio video or something which might make the problem harder, but traffic analysis would still be pretty interesting. Perhaps what's happened is that they initially 'marketed' the thing at criminals, but it's now seen take-up amongst too many other people so they can't find the signal from the noise? In which case there's presumably another tool being marketed to criminals which has replaced it.
