Today I learned. I always thought it was some “electricity magic thing” like additional heat generated within the power strips causing issues between the connected devices, but this makes a lot more sense than whatever I was thinking of.

Although I do think I might have mixed some things up between regular power strips and those outdoors/industrial ones with a long (double/triple digit meter) rollable cable which my dad was a big user of back when he used to work in construction. Basically back when I was little he used to tell me never to plug power tools into a rolled-up “power wheel”, and I think that when I was later heard you shouldn’t daisy chain power strips I must have made that (wrong) connection.
