"Many" <-- what data do we have? How many do we know where able to parlay this portfolio to fruitful careers? Some could be still at Waffle House for all we know..
Off the top of my head, just thinking about some of the LittleBigPlanet modders who got jobs to work on LBP2, or the folks who made Counterstrike (a mod) and then got careers out of it (not every single one of them, I'm sure).
It didn't take much googling to find a recent article on it:

It is narrow-minded, selfish and presumptious to decide for modders what they should get out of their work and what they hope their niche can turn out to be.
I'm not deciding anything. It has already been decided that they don't get paid for their mod work. What I'm arguing against is a system where the mod community is in the gaming company's back pocket. You seem to feel that there's some social injustice being finally rectified here. On this point we disagree.
But in another respect, I do agree: It is narrow-minded, selfish, and presumptious to place a monetary power over the modding community and put that in the hands of gaming corporations.***
What happens when certain modders - paid ones - get preferential treatment on the sites that host the content? Oh, say goodbye to third-party modding sites, by the way (at least, for any games that support this). But what happens? Does that mod just magically happen to find its way to the top of "most popular mods" lists? Does the company promote it? Does "SkyUI" come out in Elder Scrolls 6, right at launch, as a Bethesda-sponsored mod for $4.99? Sounds about right to me. Certain modders benefit but the majority will be pushed into obscurity. It's just a way to further monetize the mod scene. Valve Corporation has already been doing it for years so I guess it's all good...
Because of not wanting modders to have a choice how to get paid for their work.
You actually have this completely backwards. Money comes from customers. Customers buy the things they want. It's not like gaming companies have modders in a basement somewhere locked up doing free work. This is pro bono. Free. For fun. For the pleasure of doing it. Take your pick, but there's no product in there. Each and every modder has the choice to make the mod or to do something else. Maybe go to the park and meet a new friend, or learn chess, or whatever. There's nothing at all that is forcing modders to pick apart a game and change it.
As such, why should they be paid? I'm talking about basic business/economy here. Why should modders be paid? On the merit of the quality of their work? Yes, in an ideal world they should be paid for that. But that still doesn't answer the question of why a pay scheme should be placed in the hands of the corporations who make the games.
***EDIT: might as well further explain, for those who've decided to read my post. What happens when a voluntary community gets a bit less voluntary because money got involved? Does it thrive? Consider those who've gotten jobs from the mods they've created. From the company's perspective, why hire anyone when you can pay them a portion of that salary for their work with no liability and none of the stipulations that go along with hiring an employee? Paid mods would greatly reduce the number of people getting hired from the mods they created, while limiting them to a marginal existence making peanuts on fees from paid mods. It benefits the company and it benefits a very small segment of modders while cutting out a huge portion of the community with one fell swoop. And this is good for anyone how?
How would it affect gamers? Well, for certain you won't be getting any more mega-mods. You won't be getting cross-modder help trying to make such-and-such mod work with another mod. Goodbye to super-mods in Elder Scrolls or Minecraft that include all the extra weapons, and the UI tweaks, and the textures, etc that were made by other modders. Say goodbye to those little fan-made tweaks to existing mods that make them a little bit better. It's all paid, and other mods are your competitors. Instead of a collective spirit, you have a competitive spirit. Tell me where this is not the case. Show me an artistic medium where artists DON'T compete against one another once money gets involved. I'm sorry, but that is reality.
I am offering nothing profound here. This is a very straightforward history lesson. This is how these sort of things tend to go. Tell me again why paid modding should be under the control of big companies?
