Wheneve I see this I my reaction is that 190 is not so hot for a coffee. I know thatts not the point here but cant help it. Just because its "close to boiling" and they show an image of a temperature gaugr with "as hot as the sun" doesnt make it crazy hot.
My keurig goes up to 192, and I find the coffee to be not hot enough
Your keurig comes out at 192?
To be clear, there's a difference between the brew temp (which is the temperature the Keurig heats the water to before pumping it through the grounds), and serving temperature.
But even with that, the reality of the situation is that coffee is supposed to be brewed really hot, and many if not most prefer to consume it very hot as well. They still serve the coffee that hot, they just have better warnings/disclaimers.
