I saw that one. It's what I was referring to when I said "saying you want to 'avoid alienating people' when closing a PR that aims to improve inclusivity is more than a little pathetic." Criticizing the maintainer response there was one of the good parts of the blog post.
But the outcome of that doesn't really much change the fact that the sarcastic PR was sarcastic, and thus calling that PR spam is reasonable, whereas claiming they called the trans woman herself spam is not. To be clear, however: I've no issue with the sarcastic PR itself, only the framing of it in the blog post.
