Oh, boy, look at all the people who have
finally found a relatable reason to
hate Bethesda/Valve! I see the usual misreading, misleading, and rumour mongering is going on, too.
Neither Bethesda nor Valve have announced anything about making pay-for mods. All they've said is that the Creation Kit has the option to let you instantly upload mods to the workshop, which is pretty neat! Behold, the
official word on the subject.
Steam Workshop – We’re excited to share news that we’ve been working closely with Valve to integrate Steam Workshop into the Creation Kit. Using the Workshop, you’ll have free user content with the push of a button. The Creation Kit will bundle your mod and upload it to the Workshop, where everyone can browse, rate, and flag mods for download. You’ll be able to do this from any web device, including your smartphone. Like a live Netflix queue, when you fire up Skyrim, mods you flagged will be automatically downloaded and installed. Everyone here is really excited about the opportunities and possibilities this opens up for our entire community.
Prefer to use existing modding sites? Not a problem. You’ll still be able to upload/share/access Skyrim mods on fan-created mod sites.
Bethesda Game Studios announced today that the PC version of The Elder Scrolls V: Skyrim will be using the Steam Workshop, making it possible for users to submit, browse, rate, and download mods for Skyrim through Steam. Bethesda’s thriving modding community has been creating some of the most inventive, unique, and compelling user created content around. We’re excited to be providing the framework to make distribution and consumption of this great content easier than ever.
If you're going to take that as a sign of "now you're going to have PAID-FOR MODS!", then you're either the sort that already hates Steam (FIGHT THE POWER! Yeah...) or simply cannot read. Besides, weren't most of you complaining about the Nexus some time ago? Next thing you're going to be complaining that there's a Construction Kit at all, and that you liked it better when nobody could mod the game.

Also, note that this has
automatic mod updating - without having to go through hoops trying to use programs that don't work!
I bet it doesn't have terrible moderators, too.Steam isn't going to host content for another publisher simply because they are so good natured.
You must not know much about Valve.
