From VF (the she they refer to is publisher Nan Talese):

She was disgusted at the spectacle Oprah was making, appalled at her manners and at what she allegedly told Frey after the show was over: "I know it was rough, but it's just business." Winfrey denies ever making such a comment. "Once again, the truth is not being served here," she says in a statement to Vanity Fair. "In 22 years of doing this show, I have never said to anyone, 'I know it was rough, but it's just business.' This was beyond business. This was about the trust I share with the audience who faithfully supports the Book Club and buys the books I recommend; and based on that trust, I thought we were owed an explanation about the truth of this memoir."

It's kind of like when Jayson Blair got a book deal. Like they expected him to actually write it himself?
