Why the sudden use of the "Black Jack ni Yoroshiku" manga comic art? I know the author released the entire thing with permissions to freely use the art anywhere, but still.
A family member of mine was the original author of pi-hope. He sold the company to his partner last year, so any changes in aesthetics would be due to the change in ownership.
One of the Pi-hole dev's here. The comment you are replying to is talking about the blog post about this CVE, not Pi-hole's aesthetics. (Which haven't changed, btw)
