I get what you are saying BUT what Gregg did isn't close to what the Reyna family did. Not even close and here's why.
1. Reyna screwed off in training and gave his team a big eff you. This is unacceptable on any level and none of the rest of this happens without his hissy fit. Well maybe nothing further happens but more on that in a minute.
2. The team collectively dealt with this and put it behind them.
3. Gregg goes to a leadership forum whose written confidentiality rules allow leaders to use real world life situations to help them learn how to handle this things from a strong leadership perspective. This was actually the exact kind of example that should be used in this type of situation. Unfortunately, someone who had agreed to the forum rules violated those rules and leaked Gregg's example. Now also recall Gregg did not use any names in his story but after the fact it wasn't hard for the media to put 2 and 2 together.
4. So the whole mess then becomes public.
5. The Reyna's threatening emails sent to the USSF were during the WC before all the mess with Gio became public. That to me is childish to the max, over an incident that was over 30 years ago, and in which the entire situation was something they had no business sticking their nose in. Even if Gregg hadn't used that example at the leadership forum those emails were going to get discovered. Shame on the Reyna family top to bottom.
Overall I agree, but, you're missing the earliest part of the story where Berhalter told Gio he basically wouldn't have any significant role during the World Cup before they got there, which precipitated his (inexcusable) lack of effort in training. That was stupid a stupid decision for one of your most talented players.
