Ntp is clearly both Free Software and Open Source. The license is
a straight BSD form:
General copyright and license:
The following copyright notice applies to all files collectively
called the Network Time Protocol Version 4 Distribution. Unless
specifically declared otherwise in an individual file, this notice
applies as if the text was explicitly included in the file.

I don't see that it does, but even if it did it would still be Open
Source..

The above BSD-style license is as standard as it gets.

How do they fall short?
