"I'm sad to leave, but it was time to go. I will be rooting for those still fighting the good fight," Ryckman tweeted.
The Post published an editorial on April 6 headlined "As vultures circle, The Denver Post must be saved," calling on Alden Global Capital to sell the newspaper after it cut 30 more positions in the newsroom, leaving it at a fraction of its size just a few years ago. Editorial Page Editor Chuck Plunkett did not inform the newspaper's editor or owners of his intentions to publish the editorial.
He resigned after he said another piece critical of the company was rejected.
Alden owns a controlling interest in Digital First Media, which owns the Post.
Lee Ann Colacioppo, the Post's editor, did not immediately respond to an email seeking comment.
