YOU ARE CORRECT, SIR !
Greediness has motivated the Watchtower to do this across many decades.
Many years ago, they continued to 'sell' the "Comfort for the Jews" book long after they
rejected Zionist prophecy. During the eighties, they continued to 'sell' off various publications
that contained the failed 1975 chronology as well as other books that 'sold' poorly
- until they got rid of them. They also published other works lacking in content or quality
simply to get money from guillible publishers - such as "Holy Spirit" or the horrendous
Byington bible.
