Dear Harmony Gold,
So you have reared your ugly, spiteful, malicious head yet again, to "protect" Intellectual Property that quite frankly, should be on the verge of becoming public domain. Because you waited until Harebrained Schemes got their Battletech game into beta testing before asserting your IP lawsuit, it is apparent that you waited for a timing that would cause the most damage to the project. Your demands at this stage puts HBS into into the difficult choice of either paying your extortion, or conducting a major rewrite of the software so as not to infringe on your IP. Either of these choices could force the abandonment of the entire project, thus leaving in the lurch thousands of Battletech fans, deepening their already bottomless hatred of your company.
I have decided to proudly display my collection of Unseen Mechs, most of which I have had since the 1980's. I have also decided to suggest that you take that lawsuit, carefully fold it until it is nothing but sharp corners, then forcefully shove it through and past your rectum and don't stop until it reaches about about halfway through your large intestine. I have a broom handle I am willing to send you as a tool to help you reach that goal.
Sincerely, go screw yourselves.
