In other words, "It's always been this way, therefore it shouldn't change"?
More like "It's been this way for a long time and that way works, you don't have to do it the other way to get money (seriously), and doing so is extremely inadvisable for a laundry list of reasons."
Money = good, and I think everyone should be paid for their work. I personally don't like taking previously free content and putting it behind paywalls (and ask anyone with experience. The community doesn't like that either). It's like a GOOD free-to-play game; you can make money off of it by relying on a combination of good-will, interesting incentives, and disposable income... WITHOUT ****ing over the people that can't afford your content. Who serve very important roles such as advertising, feedback, assistance, idea generation, and even "content" for the paying customers in some cases (like PvP games/mods).
But I will never, ever, get behind taking options away from people. 0 money to ANY AMOUNT OF MONEY is a very large jump in many ways (not limited to actual effort of payment and security issues) when you're dealing electronically — someone brought up adding a paywall on one of the discussions on this topic somewhere (I've lost track of which one is where... I think I've been having this conversation in 7 places now) as being almost the same as a price hike. It honestly isn't, no money to some money involves a lot more in infrastructure and effort (at payment) than even 1 tiny denomination coin (pence, penny, whatever) to 100 (or a thousand) euros/dollars/pounds.
I think in one of the reddit threads I brought up SkyUI as a good example of the way to handle paywalls. NEW content is being placed behind the wall, and the old content is staying free. In addition, going above and beyond, the author is backporting some (or all) of the changes the paid version is being used to finance. I don't believe anyone should take DOWN content they have given freely for any reason which they have control over. I understand hosts going down and all that jazz, but what was once free should remain free. A large majority of free licenses are irrevocable, it's not like I'm spouting new age nonsense here. It's a well-established trend in all sorts of venues. But like everything else dealing with longstanding property laws/rules/regulations/expectations, digital screws with things because of the infinitesimally small cost of copying, transmitting, and storing data.
I *want* modders to make a living off of what they're doing assuming they're actually putting forth some effort. I just don't like them screwing over their current userbase to do it. That's it.
