Though because that license says "for any reasonable purpose" it's something that's vague when it comes to "is this FOSS" as it's vaguely Crockford-like ("this software shall be used for Good, not for Evil").

The [OSI requires](https://opensource.org/osd/):

> 6. No Discrimination Against Fields of Endeavor > The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

[GNU/FSF](https://www.gnu.org/philosophy/free-sw.html) have as "Freedom 0":

> The freedom to run the program as you wish, for any purpose

So honestly I didn't read the "COPY.TXT" .. I wouldn't expect a license to sit there, and I didn't consider that a license personally, I was expecting a defined license.
