I don't think this is exactly a story full of heroes - a journalism outfit that burned a source (who is now serving time) vs its crank founder. I don't know how familiar you are with Greenwald's work over the years but the reason the tantrum and 'says anyone who disagrees with him is conspiring against him' charge still sticks is that it represents a long pattern of behaviour on his part. There are, like, twitter parody accounts about this!
If you want to compare this with a similar recent situation with an actual high-profile journalist and real high-profile story - Ronan Farrow and his former employer NBC are still bickering over whether NBC unethically spiked his MeToo reporting. I don't think at any point either side has emitted a Greenwald-style screed-de-coeur, despite the bitterness of the dispute.
