He logged in and changed the password after the board emailed him and told him his services were terminated. That includes/specifically mentions his on-call services. His response claims only silence from the board and that he was just performing his on-call duties.
I've been a corporate stooge for 25 years or so now. On call duties are one of my main responsibilities. I would NEVER probe out which logins I still have access to after receiving notice of termination. He admits to doing this in multiple places.
All his justifications are that he was under contract to do work that he was already notified was terminated. Everything that follows either tells me that he has bad judgment, that he's lying (by omissions), or in the worst case totally delusional.
If he was so worried about operational takeover, why did he _change a password_ without notifying anyone else with operational capabilities that he was doing so? Nobody reasonable would _ever_ do that. There's a certain amount of upfront communication and CYA required of reasonable actors in this space and he doesn't have it (Not that Ruby Central did any better).
So no, I won't be changing my mind, and I don't know why you put "(again)" in there.
