I voted yes, they should be banned. I bought one years ago for my younger dog because we were doing a lot of camping in areas where there were some dangers, like fast running rivers, etc. We were the only ones who used the remote control, usually me.
It was kept on a #3 setting, highest was 10. I strapped it to my leg to feel the intensity, it was mild. It did get the attention of my dog and worked very well when I wanted to be sure she came when needed. I didn't use it very long, she was well behaved and learned how to stay safe.
I had it in the closet for awhile and ended up throwing it out. In the hands of the wrong person, someone who does not love their pets, or has anger issues, it can be used to punish or torture. That is why I voted to ban, too many jerks out there that would misuse something like that.
As far as barking, I think there are collars that squirt out a scent to get their attention and stop the barking. I've trained all my pups when they were young, the 'no bark' command, pet owners need to take responsibility in training and not be lazy about it, the animal always suffers.
