I also want to add that I am very sympathetic to the quandry faced by people who have repaints of these products for community sharing that are now going to be discontinued.
As someone who has repainted content for flight simulator and train simulator I am well familiar with things like others taking content and credit for themselves, and the frustrations when a product is discontinued. I also have Streamlines purchases being discontinued by this move and I hope they will reappear for OR with updated physics.
Ultimately though, I trust the Trainsimulations team/direction to do what is best long term for their business that I hope will be around developing new products well into the future!
