I think it goes without saying, that being an AVN Dev is incredibly dangerous!
But seriously, I don't think this Dev has a history of lying like a lot of other Devs do, but I'm not really in the know (I check the discord very very sparingly).
From what I can gather Yuno is bad with communication. If the recent accident is legit, then I wish them a speedy recovery. Sometimes life sucks. At least they said the game is on hold rather than some fantasical story about the update being close to done. Because that's exactly what a lot of the known scummy devs would have done.
Anywho, time will tell.
