At the Spanish forum, a few years back there was a big controversy around Raymond Franz and his books, some of the participants were of the opinion that his books should be available for free.
A wealthy Spanish exjw tried to negotiate with RF and offered him a substantial amount of money for the copyright, that was not accepted and RF position was that he wanted full control of his writings.
There was a lot of opinions about this matter and the discussion became so heated that some of the friends left the site for good. Looking back I think that RF was handling his work as a "mom and pop" operation and was not aware of the tremendous value of his writings; the arrangements after his death are a reflection.
At this time his will and desires are to be respected hoping that in the near future the pending matters could be solved and the books will be available.
