Google as a problem

Google has a market share of almost 95% in Germany. A monopoly position can be problematic in several ways:
– Quality of information <- >Advertising.
– Information bubble, if search results are displayed according to previous searches.
– Dominance of the advertising market and online market.
– Social and political aspect: Can political opinion be influenced or even controlled?
So the question arises:
– Can’t other search engines be used? How are their search results to be evaluated? What standards are applied?
– If the search results of the other search engines are not sufficiently suitable, does not an alternative have to be developed by public means?
– If the USA dominates the search engine market with Google and Bing and China with Baidu and Russia with Yandex develop search engines, is it not already necessary for this reason to develop a European search engine?
There are completely different aspects of the subject that we want to examine individually.
