This may come off as blunt, but do you intend to endanger them and prevent them from actually learning something new as well, if they can't enable an option setting I truly feel sorry for them. I hope this point is basically made by now. Turn off DHT and let the users decide how they will be seen or used by others. This way the client is not making the decisions. If you want to inform more people about DHT, great... just don't force it upon them first.
