It's source-available proprietary software, not closed-source: https://github.com/realnc/frobtads/blob/master/tads3/LICENSE.TXT https://github.com/realnc/frobt

  Usually closed source simply means it's not open source. Since it is not open source, I I think many people would normally call it closed source.

    I think this is an excellent reason to avoid the term “closed source”.

    "Open source" is widely accepted to mean "licensed under terms that meet the Open Source Initiative's Open Source Definition", instead of the obvious meaning of "source available", only because many people put a lot of effort into correcting everybody who assumed it was plain English and not jargon. "Closed source" has not had a similar education campaign, so it still defaults to the common-sense meaning of "source not publicly available". The opposite of "open source" is "proprietary".
