Do you think that source contradicts what I said?

Mr. Miranda asked Ms. Wasserman Schultz whether they should call CNN to complain about a segment the network aired in which Mr. Sanders said he would oust the chairwoman if he were elected. “Do you all think it’s worth highlighting for CNN that her term ends the day after the inauguration, when a new D.N.C. Chair is elected anyway?” Mr. Miranda asked. Ms. Wasserman Schultz responded by dismissing the senator’s chances. “This is a silly story,” she wrote. “He isn’t going to be president.”

Shocking. She didn’t speak kindly of a person who publicly attacked her, and opted to leave the story alone instead of doing anything.

Same information, but cast with additional context

Most of the shocking things mentioned in the emails were only mentioned, and are then dismissed.

Your mistaking opinions and preference bias, which all people have, for unfair bias. Do you actually expect that the people who run a political party don’t have an opinion about politics?

The coin thing didn’t happen.. At best she won six out of a dozen, which is what you would expect. The reality is more complicated.

You grossly mischaracterize the agreement.
From the article:

This does not include any communications related to primary debates – which will be exclusively controlled by the DNC.

Nothing in this agreement shall be construed to violate the DNC’s obligation of impartiality and neutrality through the Nominating process. All activities performed under this agreement will be focused exclusively on preparations for the General Election and not the Democratic Primary. Further we understand you may enter into similar agreements with other candidates.

HFA will be granted complete and seamless access to all research work product and tools (not including any research or tracking the DNC may engage in relating to other Democratic candidates).

In other words, her campaign agreed to give the DNC money to prepare for the general election, and in exchange they got to look at those preparations.
This was definitely the Clinton campaign assuming she would be the candidate, but it’s not exactly a smoking gun for financial impropriety regarding the primary.

Honestly, if your campaign can’t find a lawyer or accountant who can understand campaign finance management, you probably actually shouldn’t be in charge of a country. The financial arrangements weren’t particularly obtuse or obfuscated for moving millions of dollars between multiple political entities in multiple states.
