Taylor Swiftreceived plenty of support — and backlash— when she publicly called outScooter Braunand Scott Borchetta after news of their $300 million deal went public.

But despite any negativity she may have received over the last week-and-a-half, Swift isn’t backing down from her claims, a source tells PEOPLE exclusively.

“She has no regrets expressing her thoughts about Scooter acquiring her music catalog,” says the source. “She wanted to share her truth with her fans.”

After Swift claimed she learned of the sale of Big Machine to Braun, 38, with the rest of the world and accused the manager of “manipulative bullying” over the years via a Tumblr post, it’s been agame of he-said, she-saidbetween the singer, Braun and Big Machine Label head Scott Borchetta, who first signed the superstar when she was a teen.

Last week, the singerdoubled down on accusationsshe made via her post that she “wasn’t given an opportunity to buy” her “life’s work.”

“Scott Borchetta never gaveTaylor Swiftan opportunity to purchase her masters, or the label, outright with a check in the way he is now apparently doing for others,”her lawyer Donald Passman told PEOPLEin a statement.

Asource previously toldVarietythat Swift had to sign a deal that would bind her to Big Machine or its new owner for another 10 years in order to buy her masters or the label.

Big Machine Label declined to comment, and neither Swift nor Borchetta have commented further about their failed contract negotiations — including the specifics of any offers that were made from either side — last year.

In his letter, Borchetta, 57, claimed the deal he offered Swift gave her “100% of allTaylor Swiftassets … to be transferred to her immediately upon signing the new agreement.”

“We were working together on a new type of deal for our new streaming world that was not necessarily tied to ‘albums’ but more of a length of time,” he added.

In her Tumblr post, the Grammy winner, 29, said the deal she was offered involved earning one album back for each “new one I turned in.”

Swift, whosenew albumLoverhits shelves Aug. 23, said learning that it was Braun who had ultimately purchased her masters from Borchetta was her “worst nightmare.”
