The article in '95 opened the floodgates and I suspect that the motivation for the 2005 WT was to try to damp down the tendency among JW parents to encourage higher education , rather than a "tug of war" at HQ. I am always puzzled by the arbitrary distinction between "vocational" courses (which are OK) and academic courses (which aren't). In my limited experience , the kind of associates that a young witness would have at a technical college would be far more damaging (in witness terms) than those at a university.
In any case , JW parents & youths (ouch) tend to vote with their feet on this issue. I know many devout JW parents who kowtow to the WTS on every issue and who would never criticise or listen to criticism of the WTS who have sent their children to university.
