I think it is a big mistake to make "recasting" a black and white ethics thing, because the whole hobby of copying someone else's intellectual property is not essentially ethical to begin with, as has been pointed out before. Even that has varying shades of "ethicallity" to it depending on if the creator is making it for themselves without profit in mind, or as a way of making large profit without compensation to the rights holders, on the other end of the scale.
"Recasting" is a community law, that helps keep peace in this place, and in the prop making community. It was probably originally meant to keep fights from breaking out at conventions. Some have compared it to "Honor amongst thieves". To say that it is okay to copy a studio piece, but not a copy of a studio piece copied by someone else is absurd to anyone else but those in this community. The problem is that those without access to the original can profit as much as those who do, and that is a bit unfair, and even lazy.
The important part of this law is that people need to know about it first, and I am sure Sid did not know it at first. He did later and had offered compensation to Rich, but Rich wanted more than he thought fair. The reason Rich asked so much is that this IS Rich's livelihood. While in the past competing model makers would pay each other off with a few kits and casts of each other's work. Rich needed more to stay afloat. Sid also was getting support from many people here in the RPF, and possibly even staff at the time, confusing him even more on the "prop laws" he was supposed to be breaking.
Siderio had told me he was less about making a profit than filling a niche, and making the best model he could with the resources he had available to him. Rich himself had also said that it is okay to use an older molder that is no longer being made, and Sid's base was Rich's old V3 gun. Rich was already onto V4 and working on V5. At this point now it is a 13 year old version, though only about 5-6 when Sid started.
On the counter point, Rich is still using parts from that gun himself. Original gun parts that had to be extensively cut down to fit, even to just enough of a unique way as to distinguish them from the real gun in some almost major ways. If this was a court of law Sid would definitely be guilty, but as a profiteer, just making cash off of an easy recast off of someone else's work without doing their own work, he certainly does not fit that bill. The same could not be said for the new seller of these props.
The few good things that did come out of this is that Rich is now offering metal kits, and has fixed some of his previous problems with his replicas. Still I think Rich needs to do more to improve his model, and help market it, but he seems to be on the right track. Hopefully dragging up old issues doesn't derail him.
