Richard Oliver once again you could not be more wrong. Consider the following statement -
You might think bullying is worse than ostracism, but recent research suggests that being frozen out is actually more painful. From social exclusion on the playground to being ignored in the workplace, ostracism is among the most devastating experiences we can endure, deeply connected to our most fundamental human need to be recognized and accepted. Ostracism can reshape the human brain, and in extreme cases, even make a person want to go on a killing spree. Isn’t it time we knew more about it?

Even at my child's primary school they teach that ignoring someone is a cruel form of bullying, can I ask, do you think scientology's disconnection policy is cruel or fair?
Regarding the announcement it's obvious it means shun or be shunned, there are loads of former jdubs that aren't shunned, but try having a friendship with someone who's been announced and you'll quickly be on the end of congregation discipline. The statement 'let him have it' could mean pass him the ball or stab him to death, one is innocent and the other is not. To say the announcement that someone is no longer a JW is merely a true statement is intellectually dishonest.
