It didn't really cost them any money, you can upload for free on their beta server just the same really. Less they closed that as well. All its really done is well make it slightly more annoying for builders thats all really. Or one could argue that sl is trying to profit off the mistakes of builders.. Either way seems a bit silly to have it removed in the end it wasnt doing much harm and sure local textures work well enough but as thought only you can see them, so if your building for someone else there's no longer a good way without uploading textures to show them before making a final product less you build in beta.. And well beta's about a mess really.
