So are you saying no one boils water to make coffee?

Strictly speaking, one shouldn't boil (100°C) water to make coffee†. The SCA recommends a water temperatures of 200°F ± 5° (93.0°C ± 3°): * https://sca.coffee/research/protocols-best-practices https://sca.coffee/research/protocols-best-practices Of course the temperature you make coffee at, and the temperature you serve coffee at, and the temperature you drink coffee at, may not all be the same. One should also keep in mind the serving container: some retain heat more than others, and so the temperature drop gradient may be different and should probably be considered as well. † Making (black) tea is something else.

You shouldn't use boiling water to make coffee unless you want it to be bitter. General rule is you want 195-205F water, so you boil, wait 30 seconds, bloom the coffee, wait another 30 seconds, make the coffee. Finished coffee is around around 185-188F when I use a french press or pourover, I assume the air, container, and the grounds all absorb some of the heat. After about 5 minutes its a very drinkable ~160.

  Weird how every espresso machine in existence has a boiler in it huh. Someone should tell the manufacturers they are doing it wrong.

    Show me a high quality espresso machine that at the time of extraction has boiling water contacting the portafilter. I'll save you the trouble, because no such machine exists.

      My point was it’s very obvious that boiling water is part of making coffee I’m shocked at the willed ignorance so that we can all pretend McDonalds was negligent. But it’s mental gymnastics. I’m not sure why. I assume some anti-corporate/big company sentiment.

        I don't think it's mental gymnastics. The key fact of what I'm trying to argue here, and the lawsuit against mcdonald's, is that at the time, McDonald's was keeping the resting temperature of the coffee far too hot. Not only far hotter than any other location in the same town that sold coffee, but also, as I'm trying to demonstrate, hotter than coffee produced in a normal pour-over process. It's unreasonable for customers to assume that McDonald's coffee is significantly hotter than every other coffee on the market, and also hotter than fresh coffee they make themselves at home. I don't really have strong opinions on the "McDonald's kept the coffee near boiling so that people wouldn't request refills in store" bit, since it doesn't make a whole lot of sense as black coffee is dirt cheap and making it hotter only encourages people to consume more cream, which is expensive. Reasoning aside though, it's pretty obvious why McDonald's was found liable.
