No, he announced that anyone wishing to be released from an NDA could contact the company “and they’ll be given a release”. He very explicitly did not give a blanket release, and we have no way of knowing whether anyone requested but was not actually granted one, because they would remain under an NDA.
(He also deleted the statement as soon as he dropped out of the race, so I have to link to Wayback Machine.)
