According to the report, the revelation from Parler came in a statement attacking other social media sites where, as Mashable explained, "Parler accused the Big Tech companies of trying to scapegoat the right-wing social network in order to avoid accountability for their own roles in what transpired on Jan. 6 when supporters of then-President Donald Trump violently stormed the U.S. Capitol building."

Included in that letter was an admission that Parler "referred violent content and incitement from Parler's platform over 50 times before January 6th" as well as "specific threats of violence."

That set off Parler users, with one responding, "So you are snitches over nothing but democrat conspired bs???"

Another user echoed that sentiment, writing, "I don't like snitches," with another chiming in, "Let's go one further... f*ck Parler, the 'new twitter'."

"I tend to agree. Parler is a disappointing Free Speech platform," wrote a user which led to an approving, "This is NOT an example of a free speech platform. Parler is a fraud."

As for Parler's explanation why they shared info, one commenter stated, "To confirm, you are calling for an investigation into big tech collusion while you are colluding with the FBI against your platform members?"
