Some have said "They didn't like the way others played across the pond when they didn't owned the rights, but has turn into the very thing they complained about, once they did. Always afraid someone might make a dollar on a topper, shooter rod or a sticker. Some people have nothing better to do with their time.

But, I am still guessing oh who could it have been. Hmmmm I am right there wondering with you.

I think for the most part people follow the rules. Most who do mods are trying to make the game more interesting and down right cool. Great for the hobby. However, sucks for the pin maker that might not get a cut of the $40.00 dollars they didn't make. I wish they were as passionate about getting their games made from deposits they have taken, as they are chasing $40. That goes for all pinball makers NOT just 1.
I could totally understand if I were in my basement making a game out right and selling it to the public. That's one thing, but the chase a guy down that made a shooter rod/target sticker a topper or something so mynute. IMO (only) more about egos and self-righteous ownership than it is about a company or staying focused at the goal at hand. But that's what you get when you got company owner(s) that has nothing better to do with their time.
