Not expressing any opinions on this but it's not pure black. The shade used is #1e2327 or rgb(30,35,39)
Edit: also 255,255,255 is white, not black.
I think you really need to re-calibrate your monitor.

It's black, but not #000. It's a different and lighter shade of black.
255,255,255 is white.
The text is 0.75 white. The header background color is explicitly set with hex.

and it's totally fine it's not #000 - total black doesn't happen in nature so it shouldn't be used in design - personally, I always use for example #111 ;)
It looks jarring to have a top bar that has such a high contrast with the rest of the page. Not to mention the color palette used is very...odd. Very off white and pure black (255, 255, 255) do not go well together. They could have at least made the entire site dark themed in which I doubt there would be so much drama around it.
