I do not see how this can be considered circumvention or contempt. Google has a long history of being transparent in this way. They make public what content they delist because of copyright violations and it is only right that they inform a website when they do similar for "right to be forgotten".
Further, if you read Google's document they indicate that in the case of data protection removals they inform the webmaster of the URL that has been de-listed, with no information about the details of the request or the requester. This seems like a sensible and serious attempt to balance the right of the webmaster to know that his content is no longer being indexed (for some searches) with the right of privacy of the person requesting removal.
It also seems to be the cause of the hoopla a few weeks back which put Google in the crosshairs of many who claimed the company was trying to sensationalize the removals. Google had removed the link when the searched topic was the name of a commenter on the article (who asked for it to be removed), but not when the searched topic was person the article was about, or other relevant terms. The webmaster saw that the URL had be de-listed for some searches and the paper wrote an article about how the URL had been removed entirely, even though it was obviously in the public interest, asserting that Google was intentionally removing things that weren't justified under the law in order to provoke a backlash against it. The assumption that it had been removed entirely was incorrect, of course, but Google couldn't provide information about the rationale or scope of the removal without violating the privacy of the requester.
I, personally, think the "right to be forgotten" is ridiculous, but it appears to me that Google is trying very hard to comply with it, letter and spirit.
(Disclosure: I'm a Google employee, but I have nothing to do with any of this and know nothing about it beyond what I read in the press. Also, I'm not a company spokesperson of any sort; they pay me to sit at a desk and pound out code.)
