That article claims that Google regularly returns result pages full of ads, and shows a screenshot of a search for [what is bitcoin] as evidence: http://i.imgur.com/eBtzYic.png
Obviously a non-commercial query like this should return few (if any) ads, so I tried to reproduce the author's results. Here is a screenshot taken of searching for [what is bitcoin] in a fresh Incognito window: http://i.imgur.com/KfY3gvs.png . There are no ads, and the search results a reasonable.
I thought the vastly different result could maybe be a result of searching on google.com vs google.co.uk, but changing the domain did not generate any ads either: http://i.imgur.com/5gcOvtJ.png
Does anyone on HN see a page full of ads when they search for [what is bitcoin]?
