Everyone is entitled their opinion, and they're just that opinions no one more correct or better than the other. Dicor or Eternabond tape, each will do the job it's intended for, pick one that works or makes sense to you and use it.
I do the Dicor maintenance but also have the tape for incase emergency. I have never had a leak and thankfully have never had to use the the tape for an emergency.
So no need to get defensive when someone disagrees with your method.
