Sounds like the old dude knows what he is talking about. From those links it looks like the best plan of attack is condoms for high risk people and partner reduction strategies for the general population. The condoms for everyone approach seems to spend time and materials ineffectively.
The old dude has been abstaining from sex as long as he's been celibate (so he says), and has no sense of reality on the ground, and uses his influence to discourage the use of condoms on the grounds that there are 'better solutions', which are wholly unrealistic in practice, but suit his agenda.

To willfully ignore the reality on the ground is stupid at best and criminal at worst.
