I can't really comment on the SP Patent stuff since I wasn't around for it.
However, I can agree with you that we should focus on the product at hand than the past directly. On the contrary, I can see how people are still bitter and why that would be so.
From every SP/GOG thread I have seen, I believe the controversy comes with the territory.
Personally, I am a GOG/SP/DLX dealer. My first marker was an upgraded impulse that shot a hell of a lot better than every other marker I have shot to this day EXCEPT for maybe a victory that was tuned to perfection. (Yeah. Better then my Prototype Luxe, G6R's, Ions, DMs, NT, Egos) I'm a fool for trading it away. I try to not let the extra bs get in the way of helping people out with parts they would no longer be able to get or with helping them tech their guns. I do this for the enjoyment and fun and to make it better for players, not to sit here and moan about what has already happened.
