The petro dollar wasn’t even a thing until the 70s.

I’ll just copy a comment I made a while back. It was about the usage of “he” instead of gender neutral pronouns in the documentation:

So I looked further into this, and while I found awesomekling’s comment to be a cause of concern, I’m hoping it’s a cultural misunderstanding due to his Swedish background.

That comment is from 3 years ago, and since then there was a commit merged, that had the sole purpose of fixing these pronouns.
