Leaving

Dont tell people to shut the hell up, if something illegal or abusive is happening, transparency is needed (preferably with the wider altright if someone is using their power to protect abuse). Transparency is good, learn from the Catholic Church

An omerta just helps would-be abusers set up shop

But it isnt wrong to ask for professional courtesy and quietly leave. To not throw your former allies under the bus for good-boy points or puck fights in public fora over petty concerns. This is embarrassing, and shows that pressure works. Could also lead to dirt on you being used to dog you from then on, as a spiteful act

Private in-house disputes are best for that
