They look similar at a glance (border-top + Calluna font), so he might have taken inspiration from yours, but doesn't seem to have used any of your assets - the styles are clearly different and based on the WP 'BlankSlate' theme.
(my personal blog had a top border like that a decade ago, when styles on the body were a novelty :))
I checked the source and it does indeed mention https://wordpress.org/themes/blankslate/, but judging from the screenshot there, that theme is just really a blank theme with no style at all, and it was used to include a different stylesheet.
So, just to be clear, you are perfectly fine with someone taking something someone else created and violating the terms upon which they were given that thing?
e.g. If I took code you wrote and lets say released under an MIT license and claimed I wrote it and didn't give you any credit, and in fact released it under another license entirely, you'd be fine with that?
It's perfectly valid to criticize the original license choice.
GPLv3 is a very restrictive license, especially for what is essentially a micro blog (though I dislike the license for most open source software anyway).
Add on the original author going after a bit of CSS, not even the main effort of the project in question, and you've got my "petty" comment.
There is an artist who takes images from magazines, repurposes them for his own art, and sells them for hundreds of thousands of dollars, then gets sued by the magazines & photographers & artists, and guess what, HE WINS AGAINST THOSE LAWSUITS. Copyright is BS, especially concerning HTML & CSS code. What a joke.
Not the parent but your question and the implicit accusation is way too overblown. The design here is so generic that it can easily be used by tons of site out there. It's just a few lines of CSS here and there and if I have a design like that and come across something similar I would just chalk it up to someone with similar taste. Going out of your way to demand attribution for it is the very definition of petty.

If I released it on Github, under any license whatever? I’d more or less be expecting that.
If it was about the 4hr of work that went into my blog theme, I wouldn’t be bothered at all.
But then, I wouldn’t release anything like that under the GPL.
