Earlier quoted context omitted.
That is not what the thing you quoted says, or even correct. All duct tape is made of fabric and it is… well duct tape, so ducts were the intended use case when the name was created. Duct tape has kinda become a general term for all cloth-based tapes though, so you can indeed find duct tape not intended for ducts, but the fact the name was originally “duck tape” has nothing to do with that.
Nope, duct tape is for ducts and can't be made of cloth because the water would clearly seep through the cloth. There are strings in duct tape but not cloth. The part I quoted says that duck tape is made of cloth and therefore is not duct tape. I think people get confused because there is a brand of duct tape named Duck Tape. But even the Duck Tape packaging calls it a "duct tape".
I am sorry, but you are wrong. The term duct tape is specifically referring to “Duct tape: cloth- or scrim-backed pressure-sensitive tape, often coated with polyethylene.” We don’t even need to argue if it is good for use in ducts, it is not, I agree. However, that isn’t what we are discussing here. From Wikipedia: “The ultimate wide-scale adoption of duck tape, today generally referred to as duct tape, came from Vesta Stoudt. Stoudt was worried that problems with ammunition box seals could cost soldiers precious time in battle, so she wrote to President Franklin D. Roosevelt in 1943 with the idea to seal the boxes with a fabric tape which she had tested. … [Johnson & Johnson’s] new unnamed product was made of thin cotton duck coated in waterproof polyethylene (plastic) with a layer of rubber-based gray adhesive (branded as "Polycoat") bonded to one side. It was easy to apply and remove, and was soon adapted to repair military equipment quickly, including vehicles and weapons. This tape, colored in army-standard matte olive drab, was widely used by the soldiers. After the war, the duck tape product was sold in hardware stores for household repairs. The Melvin A. Anderson Company of Cleveland, Ohio, acquired the rights to the tape in 1950. It was commonly used in construction to wrap air ducts. Following this application, the name "duct tape" came into use in the 1950s, along with tape products that were colored silvery gray like tin ductwork. Specialized heat- and cold-resistant tapes were developed for heating and air-conditioning ducts.”

The part you quoted doesn’t say that at all. The part you quoted says “She is often misattributed as the inventor of duct tape. However, numerous variations of adhesive cotton duck tape had existed for decades, nor did she invent the specific formulation of the popularized duct tape.” Did you quote the wrong thing? It’s simply saying that the duct tape Vesta Stoud developed was not the final product we know today, nor was she the first to come up with the idea.

I honestly can’t keep track anymore.
