do modders get royalties from vbulletin?

[GoTTi]

you know, i have noticed for a long time being a customer of vbulletin that as the forums age, ofcourse it gets enhanced. almost all of the enhancements that come with the new versions of vbulletin are mods coming directly from addons users here are submitting. i just wanna know if vbulletin pays the creators for the mods, and the rights to them or whatever, to implement them in the software that keeps coming out?

if modders are ok with this, then whatever, but we all know that jelsoft is making big bucks off this forum and the enhancements it has because of the submissions from the coders/hackers here that enhance it.

someone makes a captcha addon for registeration...its now included in vb 3.7x...
Advanced Warning System was made....now it came standard with similar template information in the forum...

even though it is small stuff, the ideas and the work comes from these coders and everyone throws around the mud with copyright this and that, but it looks like with each new version of vbulletin coming out, there is another added default mod that is from some user here who submitted it for free....
