Ocean - who was nominated seven times and won two awards in 2013 - chose to not submit his second album, Blonde, for Grammy consideration because he didn't feel the show was relevant anymore.
Grammy producer Ken Ehrlich and writer David Wild suggested it was actually because he was embarrassed about his "faulty" performance at the 2013 show.
"We executed his vision knowing that it was faulty," Ehrlich said on the Rolling Stone Music Now podcast.
"And we tried to tell him that, we tried to tell his management that, we tried to tell the record label that. So, his feelings about the Grammys right now, I would imagine, probably go back to that in one way. But honestly, it wasn't us."
Frank responded to their comments in a Tumblr post, suggesting that actually Taylor Swift's 1989 album beating Kendrick Lamar's To Pimp A Butterfly to win the Album the Year award was "hands down one the most 'faulty’ TV moments."
"Winning a TV award doesn’t christen me successful," Frank said, "And if you’re up for a discussion about the cultural bias and general nerve damage the show you produce suffers from then I’m all for it."
Frank isn't the only absentee from this year's award ceremony. Kanye West, Drake and Justin Bieber are all nominated but are not confirmed to appear.
It had been reported that the three artists were boycotting the show because it was "no longer relevant".
The Grammys take place on Sunday night in Los Angeles with Lady Gaga, Metallica and Beyonce performing.

Ok Ken (and David). As much as I hate to make you guys famous or even respond to you directly. We all die one day and you’re old so f**k it. Yea yea my 2013 performance at the Grammys was absolute s**t. Technical difficulties, blah blah. Thanks for the reminder. Very much appreciated. F**k that performance though. You think that’s why I kept my work out the Grammy process this year? Don’t you think I would’ve wanted to play the show to "redeem" myself if I felt that way?
