What he believes is way off. You get kicked out for suggesting child abuse is being covered up. Or telling the elders they are behaving in an unchristian manner and being cruel. Or saying WT's 1914 doctrine is wrong.
You do, but I think the vast majority who are df'd are for more traditional human failings of sexual immorality. So no, I don't think I'm "way off" if you were referring to me.
The mistake people who leave because they stopped believing is to think that everyone else who left also thought the same way.
You only get disfellowshipped for wrong doing if it is affecting the status quo. If you want to stay in you just say the right words to the elders.
Well, there is the "sincere repentance" thing and you know what they say about sincerity - once you can fake that, you can achieve anything. But it's complex - some people may be genuinely sorry but quite rightly unwilling to submit to intrusive questioning, others aren't sorry at all but play the game or have elder daddy to clean up their mess and get to do it again (we had some who were stuck in the revolving door of membership like that)
Something else to remember: just because someone was kicked out of the WTS doesn't make them a good or nice person that we should want to be around. This is another mistake people make. Not everyone is like us.
Some people are snakes and take advantage of others. There are lots of naive, overly-trusting, inexperienced people in the WTS. Some will take advantage of those people. Sometimes the people being taken advantage of will be underage with parents who are also too trusting of others in the congregation because of their propaganda. I doubt the WTS has a blanket 100% record of covering up abuse, but the ones that are rightly shown the door don't get the same publicity by people seeking to show the evils of the WTS.
Imagine if someone was regularly cheating on their wife with "girls" and was eventually shown the door ... we wouldn't want to make a hero of such a person would we?!
