If the convoluted hilarious title didn't give it away then the 1991 quote (given by Churchill) here attributed to Albert Einstein (who died in 1955) should do it.

Yeah, probably I didn't notice subtleties at first (because I'm not a native speaker), but still satire is usually published at designated places. Imagine finding a ridiculous column under your own name on TechCrunch in Security section.

The Register is pretty clearly such a designated place.

The UK press likes to sprinkle its satire around fairly liberally & TheRegister goes for the full bore approach: Every article there is partially satire.

This is satire.

I thought so, but there's even author page: http://www.theregister.co.uk/Author/3144 , and no indication anywhere - looks like defamation case then :)

The article explicitly states that the author is not the same Craig Wright claiming to be Satoshi.
