"We", as fans, only "should" know as much as it's strategically beneficial for Fisher to say.
You keep mentioning a lawsuit, which hasn't happened yet, and I keep saying that a lawsuit is not the first step you take in a workplace conflict with a big corporation like this. I'm not overthinking it, I just know the realities of how costly and limiting starting with a lawsuit can be. The strategy will depend on Fisher's specific goals and his specific accusations. We don't know enough to make a judgement yet. And that's that. You can like or dislike what you're hearing, but we can't say for sure whether it's a sound strategy or not.
