3 other points that I would like to add:
1. Discouraging higher education has resulted in many JW's being low wage earners who are unable to contribute much financially to the org
2. Encouraging singleness / not having children has resulted in congregations comprising almost entirely of middle-aged / older ones with no future growth potential
3. The "marry only in the Lord" policy has left hundreds of thousands being unable to find a suitable marriage mate, many of which end up being single & childless while growing old & bitter. Many of those who ignore such counsel & find a non-JW marriage mate get hurt over the judgemental attitude of the congregation & end up leaving. No points for the WT in either scenario!
