I've noticed that, for whatever reason, a lot of xenforo mod/add-on developers are charging for their products. Perhaps Xenforo somehow has this as part of their business model. I'm not sure. I do know that I find myself reluctant to shell out even, say, $5 for a modification about which users in the mod's discussion thread are posting concerns and notices of bugs--not at all uncommon. This situation raises questions for me, especially since the community of vB add-on developers have and continue to offer so much of their work for free. Do you feel this community of Xenforo developers, which seems increasingly to want to be paid for their work, is actually offering better-quality mods because they're fee-based? Or is the quality no different than, say, the mods that one could get from the vB add-on developer community? I wonder, in other words, what effect the culture of paid vs unpaid contribution is having on the xenforo user community as a whole.
