"This is an apology for the way we previously handled illegally sold copies of '1984' and other novels on Kindle," the Amazon chief executive said in a post on Thursday on the Kindle Community discussion forum.
"Our 'solution' to the problem was stupid, thoughtless, and painfully out of line with our principles," Bezos wrote.
"It is wholly self-inflicted, and we deserve the criticism we've received," he said. "We will use the scar tissue from this painful mistake to help make better decisions going forward, ones that match our mission."
Bezos' apology came a week after unauthorized copies of "1984" and "Animal Farm" were wiped from Kindle readers in a move that triggered privacy concerns and drew unfavorable comparisons to Big Brother-like behavior.
