The promise of exclusives is what brought many people & $$ into the KS. I contributed because I didn't want to miss those four ships.
Their use of the molds for any other ship of the same class is up to them as long as they don't use the same name or color scheme.
What people missed out on is just a part of life. Help your friends, but don't support them.
