It’s a nice aesthetic choice in macos. They got rid of the icons, I always thought the order was clear. It’s like a car clutch closes the engine from the wheels, brake slows the car (minimise) and accelerator maximises.

You can change them to grey circles.

A big part of it is also letting other people know you did it. China and Russia are big on this. The create dangerous situations, then say they aren’t responsible all while sowing confusion. The want plausible deniability, confusion and credit for doing it.

Could be Chinese creating reasonable doubt. Making this sort of mistake makes explanations that this wasn’t Chinese sound plausible. Even if evidence other than the name comes out, this rebuttal can be repeated and create confusion amongst the public, reasonable suspicions against accusers and a plausible excuse for other states to not blame China (even if they believe it was China).

Confusion and multiple narratives is a technique carried out often by Soviet, Russian and Chinese government. We are unlikely to be able to answer the question ourselves. It will be up to the intelligence agencies to do that.

If someone wanted to blame China for this, they would take the name of a real Chinese person to do it. There is over a billion real people they could take a name from. It unlikely that a person creating a name for someone for this type of espionage would make a mistake like picking an implausible name accidentally.
