I've just accessed AvoidJW's site and, frankly, I am astonished that JW organization hasn't taken action sooner. He blatantly - and prominently - features complete stand-alone copies of copyrighted JW literature. Talk about defiance of copyright regulations. fred1 is correct: You cannot now access downloads of JW literature.
No one can claim that JW organization is trying to shut him up - they are trying to stop him replicating their copyrighted literature. He could not possibly argue "fair and proper use" for the purpose of critique.
I defy anyone here who would stand by and watch another website copy their copyrighted materials and not do anything about it.
Meanwhile, several other ex-JW websites continue untroubled by legal threats by JW organization simply because they have limited their use of JW literature to "fair and proper use".
