1) Wider by a lot. I don't have official rules set up here, but suffice it to say, don't be surprised if you get shocked by something offensive over the coming week or so. The biggest restriction is that the site does not allow porn, nor copyright violating material. My advice would be to, for the moment, think of it as Reddit, but with less stupid harassment rules.

2) Ciaramella is a problem generally because many people believed that he was a lynch-pin in fostering collusion between the FBI, the CIA, the DNC, Obama's National Security Council, and a Ukrainian "Anti-Corruption" organization that was directly tasked with fabricating the Steele Dossier, and trying to destroy Paul Manafort in order to collapse the Trump campaign in 2016. He was previously released from the CIA for leaking information to the press, was later re-hired along with policy changes that suggest to some people he was hired explicitly for the purposes of leaking information. He was in contact with Adam Schiff before he filed his complaint.

Basically, the dude is absolutely dirty, and could implicate a huge number of people.

The problem that most people are having with the coverage of the whistleblower is that he is a public figure who has been identified by Politico, The New York Times, and RealClear Investigations and a whole host of other journalists and media organizations. The largest left-wing media organizations (MSNBC, CNN, CBS, ABC, WaPo, Salon, Slate, etc) have all worked together to entirely remove any mention of his name in public to "protect his identity" although his name has already been publicly released. The mainstream media is intentionally suppressing news stories. That's what people are upset about.
