When I was there, the three most widely used languages were C++, Java and Python. So that type of language had the most data. And so the analysis that I read focused on them.

Within those languages, projects that did a good job of KISS fared better than those which didn't. This lead to a discouragement from using advanced features. You'll see that bias in style guides like https://google.github.io/styleguide/cppguide.html.

Well, none of those 3 languages are what I would consider "an advanced high-level language". C++ is not high-level by my definition and python and Java are certainly not advanced - well maybe Java has an advanced typesystem compared to Go, but not compared to the state of the art.

So I'm not surprised by the results, if the majority of the data came from those languages. That doesn't invalidate anything, it just changes the scope and can't be really used to backup your argument imho.
