Hm that must be why Starbucks drinks get cold so fast. Or maybe it's the paper cup. McD coffee in an insulated cup is still nicely hot by the time I get to work. When I make tea, or coffee with my Aeropress, I use boiling water right out of the kettle. I agree with GP, coffee should be HOT.

It will taste better if you use water that is at 90C or 194F.

Have you read the Aeropress instructions? They recommend water at 175F (80C) [1]

You can personally opt to drink boiling water directly from the kettle if you want to and there will be no lawsuits, but that's not a comparable situation.
