The moral of the story is: don't be a whistleblower unless it's for some area of industry where the government gives you immunity and a few million in cash. Or, be prepared to never work in that industry again: this is whistleblowing 101, so don't be surprised.
(Not that I think he is blowing the whistle on anything, really. It sounds like he was upset that he was fired so he tried to make his Outlook dump sound interesting enough to get himself some media attention. It didn't work.)
He also withheld information from the investigators. If you blow the whistle, you're expected to give everything up, not just the stuff that doesn't make you look bad. THAT'S why they nailed him to a cross; he tried to double-deal.
And the people who were and still are committing tax fraud on a scale that blows away what any individual could do on their own?
They're fine, thanks. The guy who tries to blow the whistle gets nailed, though.
That's not why they nailed him to the cross, that's how they did it. The why is evidenced by the fact that they're not going after the actual tax cheats in addition to him.
I think there is an important part of the story missing between: "If I wasn't blocked from the position I deserved..." and "...patrol officers came into my house to accuse me of being a terrorist."
