It is partly due to the crazy litigation in the US and the rewards people get for some coffee they spill on themselves just because the coffee was "too hot". There are two sides to this story and it is not only the business' owners who are the culprits here.

Look up that case. The victim suffered third-degree burns and required skin grafts. The myth that it’s a ridiculous, over-litigious case is just that: a myth. The coffee was absolutely too hot.

And it was caused by a profit-seeking behavior - an assumption that most, if not all people, would wait to drink the coffee until after they were out of the vehicle, which could be up to X minutes; as such they wouldn't want cold or lukewarm coffee. If most people equated mcdonalds coffee with "bad lukewarm coffee", less people would go to mcdonalds for anything, including coffee. I forget how hot they served the coffee, but it was up around 95C/200F. I know that you have to specifically request "extra hot" at places like SB and CB&TL, otherwise you get coffee hot enough to still be "hot coffee" after adding creamer, i venture 130F or so. AFAIK McDs doesn't offer "extra hot" coffee. Once bitten, and all.

I don't know about the changes made due to this lawsuit, but i reckon they changed their cups to keep ~120F coffee at that temperature longer.

edit: aside: I just realized why i prefer Fahrenheit even though i understand Centigrade. Stuff over 100F is "hotter than i am" It's intuitive in a way that merely remembering 37 is body temp (my dad was born in '37 so that's why i remember) and "anything over 40 is hot" doesn't really roll off the tongue, even though it's roughly as accurate as my ">100F is hot"
