Fortunately I set up unbound ages ago, and disabled every other upstream option in my pi.hole. However, I imagine that still “leaks” some information about my DNS queries, just indirectly – it’s not like my pi.hole has every domain mapped all the time!
It’s branding, mostly. The phones had a notch. Design language dictates that the laptops can too, since it’s Totally Not Ugly (but it is).
Also, macbooks are slightly taller (16:10 aspect ratio) than most Windows laptops (16:9). Slightly taller even with the notch, since the extra screen is on top of the 16:10. So there is admittedly not much room to fit a camera on top. Personally I would prefer a slight bulge at the top and a rectangular screen, but with a black background, it isn’t too awful. Drives me mad with any other colour, though, I just can’t unsee.
