That distribution looks all right to me
I have long stopped using any of the "competition" listed on that slide. While this may be specific to the goods I search for, their search result used to yield 90%+ duds (stuff that is no longer in stock or at same price) and/or false positives. Compared to that, Google usually hits the >50% range.
On top of that they used link spam to fill the first 2-3 pages of any search result term (regardless of how irrelevant).
They definitely will not be missed, even if all of them go under.
By the way, this does not mean that Google should not be subjected to antitrust controls - that is a given and mandated by Eu law after you gain "significant market power". Google has had that for a while now and has managed to get away with it for too long.
