Actually, Google is heavily using personalized results nowadays, and especially with the news search.
Depending on who you personally support, you might only get results confirming your PoV on any topic you Google.
If an individual finds personalization of search to be a barrier to finding diversified news, they could always use incognito and search among many different search engines for the most diversified results.
Merkel's solution to the problem is to add another roadbump via government intervention. The real solution is already in the users' hands.
Few people will do those things. Most people do not understand Icognito and won't look at the second page of search results, much less use multiple search engines. I wonder how many are even aware of other search engines.
The reality is that the search engines' personalization algorithms determine what users see.
Our two statements are not mutually exclusive.
Merkel looks at it as a problem for society - people aren't getting the diversity of opinion they should get.
If I wanted diversity of opinion, I would go to Breitbart, but I don't want to. Maybe it would broaden my perspective to do so, but I can't be arsed. I've been there once, but it was mostly an exercise in social anthropology.
