Patch 4.10 - Development Updates by Daidalos Team

[AndyJWest]

The free license does not apply to the use of Northrop Grumman’s trademarks in books, posters or calendars in runs that exceed 5,000. Likewise, the free license does not apply to use of Northrop Grumman’s trademarks for any form of merchandise such as toys, models, clothing, coffee cups, notebooks, electronic or video games, etc.

It doesn't look like the situation has changed. Northrop Grumman is still claiming to hold copyrights relating to 'electronic or video games'. In any case, as I understand it there was a legally-binding settlement reached, which presumably still stands.

Personally, I have serious doubts that Northrop Grumman's claims would stand up in court, but since it isn't my money to risk, I can't blame software developers for not taking them on. If NG want to erase themselves from history, that is their problem...
