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"
And the problem with that has a lot do with corporations. For instance, if you are a pedestrian and get hit by a car and end up in the hospital, in a lot of places in the USA your health insurance will not cover you at all -- you have to sue the driver and get compensated from their auto insurance. The logical method would be for your insurance to cover you and then the health insurance would recover costs through appropriate parties.
It is the same with ridiculous lawsuits like the aunt who sued her sister because the nephew jumped on her and threw out her back. In order to recoup medical costs she had to sue her sister since the sister had homeowner's insurance.
You can't entirely blame the legal system when the corporations are using it to perpetuate the problem for their own gains at the expense of everyone.
Don't get me wrong, I think there is some good in it (mostly around risk calculations), but the entire industry feels scummy.
The craziest example of this is how all these contracts are appearing in the physical world as well. There are stores that actually have a sign indicating that entering the store constitutes acceptance of contract terms (with a QR code that you presumably can scan with your phone to read the contract). I've also seen public parks with the same thing basically indicating that entry binds you to a legal agreement to not sue the park/follow posted rules/etc.
