Microsoft's chief marketing officer Chris Capossela has stated on the Windows Weekly podcast that the end of of OneDrive unlimited storage announcement was rushed in order to do damage control.

"The way we did communication was very rushed because a major publication was going to print something that was very damaging and was not true, so we felt like we had to get in front of it," Capossela said.
"We had given ourselves a couple more months to get everything lined up [for removing unlimited storage] so we could do it all-in-one fell swoop. We were just not ready," he said, later continuing, "We just didn't do a good enough job ... to beat the story and get the communications in the shape they needed to be."
He did not name the publication or say what the story was about, beyond OneDrive.
