Ha, yeah, I did consider getting my windows machine out for some the screenshots, then I could do light/dark win/mac. In the end, I figured the same framing was better because I mainly wanted to highlight the light/dark theming support, and "cross-OS" isn't really a feature you need to show for a website

And the screenshot on VSCode page shows Linux version. Emphasis on non-Windows applications may be intentional.

In this case I believe it’s up to the blog author. Orta is a Mac user (was involved in a package manager, Homebrew? I forgot). The VSCode goes as far as detecting the OS you’re on and shows the most relevent screenshot, so you get Windows on Windows, Mac on Mac and iPhone, etc. But yeah, even just the fact they don’t force all of their websites use Windows screenshots is saying a lot by itself.
