Wow, I am surprised to see that much Valve/Steam hate here. I don't see how this could be a problem at all, it is just another(and hopefully more streamlined) way to install mods. And about the whole "making money off mods thing". First of all, there isn't even any information that mods are gonna cost money(the EULA only say that Steam has the right to, not that Steam is going to). And it is very unlikely that if it will cost money that modders will receive nothing(Valve do have an image to protect). And if modders do receive money for mods on the Workshop, that's great. I see no reason to complain. Mods are a product, you pay to get that product. If anything you should feel lucky that most of the mods are free nowadays, I don't see why some people claim to have the right to receive mods for free.
