There are two different things..
1. Announcing someone has left the company (maybe say you wish them well in a generic way, maybe not)
2. Giving the laundry list of reasons the person left the company.
Number #2 is NEVER appropriate and often illegal. Steve was an exception because both parties agreed to share he was moving to Utah. However, the Dis has often not done #1 either so it takes much longer for the news to spread through the fandom, IMO making it worse dragging it out.
I read second hand things about Pete's solo show. I am not a Patreon so no idea. Basically, if the Dis did #1 better, in a consistent way, we wouldn't end up with people..saying wait..is so and so gone? These rumors get started every time people miss several shows. Heck, I even started to wonder about someone else since I hadn't seen them (they have since reappeared.)
There will always be trolls who are just trying to stir drama up, others are just honstly trying to clarify if they are gone or not. I trust whatever it was others seem to have heard/read. I don't need to know anymore then that and I wish him well.
