My opinion is that open source documentation is like polite dinner conversation: It’s not the proper place to discuss politics.
If an author wishes to use their open source project as a platform to discuss politics, that’s the author’s prerogative. But then, as perhaps in this instance, it could be to the detriment of the project itself.
I'm going to place the blame on the party committing the crimes, not the person exercising free expression.
So the free expression is considered by everyone according to their own ethical and moral values.
