Anyhow, the scary thing is that Guiness’ actions may well be on firm legal footing under UK trademark law. AFAIK, the UK does not have an equivalent of the fair use defense and it’s trademark laws are notoriously overprotective – they’re why the McMahon, Inc. is no longer able to call itself WWF; had that case been brought in the US, it would have gotten laughed out of court on grounds that there was no likelihood of confusion.

Additionally, a big part of the reason why there’s a fair use defense in US trademark law is that we have the First Amendment. There is not generally a UK equivalent.

I’m just not sure that Failblog would be subject to UK trademark jurisdiction, which is outside the scope of my knowledge.
