I think that leaking someone else's private Add-Ons without their permission is absolutely despicable. They should not under any circumstances be treated as a hero for doing it. Mod creators' content and the release or lack thereof is expressly their business. There is even a pretty much an unspoken rule here saying not to do it.
But,
Bushido, while I respect you tremendously as a mod creator who has brought such color to the community with such useful mods, both independent and in packages, and while I agree that you as a mod creator have no obligation to release your content to anyone, I say with utmost sincerity, have more faith in yourself, man. Like yeah you set the bar high for yourself, but people are bound to be accepting of your mods whether WIP, incomplete, broken or otherwise. I think one of my favorite things about your mods is that they are meticulously fine-tuned. But don't worry too much about what people think, 'kay?
