"What intrigues me is how the ink level detection works, because I couldn’t figure that out. I also can’t figure out why after refilling the sponge the printer still reports the ink level as low."

It's simply the printer knowing how much ink that it has printed since you first put the cartridge into it. The cartridge has a fixed volume so the firmware can easily predict the amount of ink left (assuming you don't refill it). If it automatically detects when you put a brand new one in, it's probably because the chip inside the cartridge has a different serial number or some such.

And finally, i know this printer cartridge is a piece of shit, because it's a printer cartridge and it has this logo on it.

Ink detection could probably also be done by a conductivity test.

^Surely some manufacturers must do that too.
