I have the same experience. I started to notice about 6 months ago. It's happening a lot more often that i'm frustrated with results even when looking for trivial stuff. My last search frustration was: 'bitmitigate'. I had to make a benchmark of CDN services and their company site isn't on the first page like other products i'm searching for. I suspect it's because this company had business with alt-right imageboards, but it scares the shit of me if this kind of political controversies are incorporated now in google's algorythm.

By contrast, searching 'bitmitigate' on DDG produces the expected outcome: the first result is the official .com site of the company.

(Edit: added the last paragraph comparing to duckduckgo)
