Delivering no information is less harmful than delivering false information. Currently we don't know if the information from AZ is true or false, and all are welcome to their opinions. But if his remarks turn out to be false, then he has done a greater harm than the person who contributed nothing.
Unfortunately I don't believe we'll ever know. After 15 years, those making claims have proven they can keep pushing the goal posts back seemingly infinitely.
I don't believe we get paid, I give it 3% chance of anything significant. But I've bought lotto tickets with a smaller chance of recovery, thus I still check up here once a week.
Good luck folks.
