I noticed the main place to download modules is here
some in the links section link the source which just loops back to the same page. So are all the modules hosted on github itself open source? as i see what looks like the contents of each module there.
I suppose some modules might be posted on XDA that aren't on github and i know not all Xposed modules on Xda or repo.xposed.info aren't open source.
Appreciate all help.
