I read the same announcement. Or more precisely, I read at least two slightly different revisions of the announcement (it was updated between my two passes).

Our org has ZDR, and has had it since the contract was signed. Yesterday two things held true at the same time:

    1. Fable was available if you had at least .170 CLI client; and
    2. ZDR was no longer on

By the time West Coast woke up, the admin panel apparently had an option to toggle ZDR again. It remained off by default.
