I hope I am wrong. But I don't see anywhere in the text of this license any explicit permission to use it for any purpose, it's basically only a warranty disclaimer, unless some bits were omitted by accident.
Because otherwise what is the utility of releasing the source code of a programming library for free? Could they argue that it was only for educational purposes or something?
Again, seems like a trap if it's supposed to be interpreted otherwise. In which case why should such a trap be legal.
