Well, you've got to invest in the modder to keep him/her motivated if you think that what they do i justifiable to let them know he/she is going 'right' in the direction they have chosen. I've paid for the EnduranceRacingX mod knowing that it is in a beta stage with continuous updates, just like I bought rF2 knowing it would be in a beta stage for some time. I really don't see any difference, it's just like people who bought/invested in p-cars. And speaking of that particular mod it does stand out more quality-wise than most other car mods that are available despite lacking cockpits atm. It's just more thorough then the rest.
I don't get the hysteria behind payware mods. It's been around for years in the flight-sim community, it's almost standard practice there and noone complains. I've been somewhat simultaneously involved in both communities for almost over ten years, however I'm bigger fan of cars than I am of airplanes and I've always been baffled why so much of the modding put out for sim-racing has been free. Sure it is the legal side of it, but then again I've failed to see any donation buttons from some of the bigger teams/modders that put out true quality stuff. I think it's only a matter of time when 'this' arrived and it looks like it has, I don't think it will kill the modding scene.
Passion is hard to conquer. Also, remember that GTR by SimBin basically was an improved/modified version of an ISI-engine that they charged for, where's the difference?
