Exactly. They don't even consider the long run. What about months later? If you're paying upwards of $5 to $20 or more for a mod, then the mod better fucking work properly and stay updated as the game itself, and the other required mods update as well. When money's involved something like this becomes a product, and a service. You're entitled to a good quality product that works when cash exchanges hands.
As soon as modders start selling their content they better be able to deal with criticism and start providing a long term service for their customers cash investment. If greenlight and early access has proved anything though, I have a feeling there's going to be a lot of quick cash grabs, non-refunds from valve for clearly broken products, and a bunch of hissy fits thrown by incompetent modders on the community workshop forums
