If Bernie thought it were so important to have 'neutral' members, his own selections wouldn't include people who've been attacking Hillary. This is just more of his constant hypocrisy, something is wrong unless he does it.
The whole "neutral members thing is bullshit, because he just wants more chairs friendly to him, but this:
Governor Malloy and Mr. Frank have both been aggressive attack surrogates for the Clinton campaign. Their criticisms of Senator Sanders have gone beyond dispassionate ideological disagreement and have exposed a deeper professional, political, and personal hostility toward the Senator and his Campaign
Is an accurate statement. Look, I like Barnie Frank, but he chose to take an open and aggressive stance in denouncing Sanders. Now that Sanders is in a position to make demands, he's getting the consequences of that choice. Perhaps Barnie should have been a little bit more restrained with what he said.
So Bernie in the end isn't a progressive then, and is self serving.
Bernie has a strong progressive record. He's self-serving though. The guy is a life-long politician, of course he's self-serving, right?
I still think things go according to plan. The DNC gives Bernie a few concessions, he endorses Hillary, and we unite for the general election. I doubt he's going to burn down the future for the progressive causes that he's dedicated his entire life to further.
