It is difficult to appreciate how ubiquitous swastikas are in the Buddhist world until you go there and see them everywhere. I have no doubt that this was an innocent decision.
Put another way: I cannot put my or my employer's interests in Western markets at risk because something is acceptable in Eastern markets. The maintainer can do whatever he wants to do; I'm not questioning that. I'm just saying I won't be using it, even if it would save me from sphinx-autodoc fragility.
My employer works in both markets, so rejecting something because it's Eastern would look much worse than rejecting it because someone in one market might not know what it is.
Anyway, it's a tiny icon on the boiler plate of a dependency of a project used to generate documentation. It would be a huge stretch to say your employer supports Nazis because of this.
They are paired mirror images, so they are both clockwise and counterclockwise.
