Ok, so I think the timeline is, he signed up for an unlimited storage plan. Over several years, he uploaded 233TB of video to Google's storage. They discontinued the unlimited storage plan he was using, and that plan ended May 11th. They gave him a "60 day grace period" ending on July 10th, after which his accouny was converted to a read only mode.

He figured the data was safe, and continued using the storage he now isn't really paying for from July 10th until December 12th. On December 12th, Google tells him they're going to delete his account in a week, which isn't enough time to retrieve his data... because he didn't do anything during the period before his plan ended, didn't do anything during the grace period, and hasn't done anything since the grace period ended.

I get that they should have given him more than a week of warning before moving to delete, but I'm not exactly sure what he was expecting. Storing files is an ongoing expense, and he's not paying that cost anymore.
