It's not hard to see these line of fines against Google for what they are: Money-grabbing attacks. With no knowledge on the matter, as an external observer, I wish this doesn't lead Google to de-prioritize its offerings in Europe.
I'm not sure what reasoning you're using, but it appears you aren't grasping the complexity of the argument.
For starters, Google search placement is a fundamental part of the search product, and is a wholly different product from Google Ads (which don't show up alongside search results). Search results and display ads aren't just different products--they're different markets (for example, print ads and tv ads are also advertising but are wholly separate forms of advertising from each other and from display ads and from search placement). So paying for placement in search results isn't an antitrust issue.
On the other hand, if buying search placement was contingent on also buying Google Ads, that would be a textbook example of antitrust abuse because Google's dominance in the search engine market is being used to leverage and interfere with the display ads market.
It's interesting to see how many people are shocked abuse of dominant market position remedies. I think enforcement has been so lax that many people casually assume anti-competitive behavior is the de-facto norm.
If you want to make a general argument about Search placement that is conditioned on plainly wrong assumptions (Google _never_ prioritizes organic search results based on buying Google Ads) then, sure, go right ahead.
