SnowWa, it's interesting that you are criticizing positive training in relation to housebreaking when you youself recently started a thread about your toilet training difficulties.

I don't think anyone is saying that there's anything wrong with using a collar or harness on a dog of any size. The method of leash corrections that is being referred to (which many of us consider old fashioned) is, unfortunately, still used by many trainers today. It involves leash pops which does involve "yanking and hurting" the dog. Some even use the leash to "helicoptor" the dog which means suspending by the collar to correct bad behavior. There are those who still advocate choke collars - even for Yorkies - to make all of the above even more "effective" (ie painful).

There's a huge difference in that and using a collar or harness to simply restrict a dog's freedom!
