Issue is they are not allowed to make you pay for those mods as it breaches the contract with Giant. I guess it is the part where technically Giants owns you mods and not you so you are making money off of "their mods."
But people should at the very least as OG modder for perms. I have tried with my mods but they can't be found or it is a tweak of a modhub mod. Most people are mad about that part is stealing mods they are already working on with no perms or credits at all
