He was told that after the grace period ends, his account would become "read-only". Interpreting "read-only" as "I will still have read access to the data" is not unreasonable. I'm guessing that neither of us would have trusted it, but HN readers are not representative of the population as a whole. Google should have provided explicit notice of their intention to delete the data a reasonable amount of time in advance, accounting for the amount of data involved. I don't think that a week is reasonable in any case, but it is especially unreasonable when hundreds of TB of data need to be moved.
