It seems that we've reached the DRM status of mod creators. Man..

And it’s exactly what many of us feared. I just came across this listing for this 1970 BRM P153. On the surface, it looks fine it’s listed as a $0.00 (Free) resource. But look closer at the blue box on the right: "DRM Protected Mod" "This mod must be downloaded and installed through the SimVendor desktop application for DRM protection." That’s right. You now need to install a proprietary desktop application and sign in just to use a free Assetto Corsa mod.
