My dad died in the same way the man in the article did, and I have a deeply unpleasant visceral reaction when someone says "hung" rather than "hanged" when talking about suicide. I can't explain it - other than "hung" feels inhumane and callous. (I don't even like typing it). So I agree with you, albeit maybe for different reasons.
And language around suicide is always important. I'm still getting over the idiotic term of "completed suicide". Thankfully few people use that now.
