I tried to list their motives under the GCHQ/UK motives, who would be more likely to fake the slide anyway and are the ones alleged of having leaked documents to the Independent on behalf of JTRIG, are a fairly likely candidate. Faking a slide like this would be a good way to inspire paranoia and divide a community, no? It got Cryptome to post a notice on their site for a week or two, alerting people to the possibility that they'd been targeted by GCHQ by visiting Cryptome. Sounds like JTRIG-ish paranoia, no?
