Why is Google inserting itself in the Australian mining tax debate?

Australian mining magnate Clive Palmer has been making much of the fact that Kevin Rudd is mentioned in the same breath as Marx and Engels when one does a Google search for the term "super tax".

However the first mention of this 'trio' appears to have been by Palmer himself - starting initially as a general charge of "communist" to a Bowen LNP audience on May 19 before refining to a specific association with Marx and Engels by 2 June this year in front of a National Press Club audience.

Coincidentally, the latter reference does not turn up 'independently' until 2 June, when Wikipedia finally makes mention.

When looking for references I stumbled upon this comment attached to an online Sydney Morning Herald article on 3 June 2010:

On Tuesday 1 June 2010 if you clicked he following link to Wikipedia http://en.wikipedia.org/wiki/Superprofit you would have seen Kevin Rudd's name along side those of Marx and Lenin in the first paragraph. It stated that Kevin Rudd had announced a "Super Profit tax," for mining in Australia.
I know because I sent the link to some friends suggesting that having the PM of Australia mentioned in the same paragraph as the 2 communist icons is not a good thing for Australia.
Having checked the link again this morning, Rudd's name is not mentioned and the reference to the mining tax has been removed.
I don't know if/how you can check things out in Wiki land to see what and when something was updated, but it would be great if someone could as it has definitely changed. I wonder if it was within a few minutes of Clive Palmer mentioning it at the Press Club yesterday.
Forget fighting Conroy's disastrous internet filter, Labor government censorship is happening right now.

Intrigued, I went to Wikipedia and discovered the individual who edited out mention of Kevin Rudd was USER Intelligent Mr. Toad, an occasional Wiki editor since 2004 who possibly hails from Queensland.

However, even more intriguing was the identity of the individual who first inserted Rudd's name USER 72.14.228.140, an individual/s apparently from somewhere in or near New York who only emerged on 13 April 2010 in Wiki edit histories.

Now IP address 72.14.228.140 belongs to Google Corporate It according to Whois. It's not a robot.

So why was a Google employee bothering to mimic Clive Palmer by placing Rudd in the same company as Marx and Engels?
Thought Clive needed a little help with his credibility perhaps?
