I saw the news start bubbling a couple days ago, but wasn't going to post it here. A lot of this looks like a cash grab. Will runs a tight ship when it comes to business. Additionally, he knows eyes are on him and his behavior, especially since the Oscars.
I don't know anything about Brian, nor do I want to discredit those who are victims of bad behavior, but it's hard for me to believe this is true. So much of it seems like he's trying to build something out of nothing, or very little. Will has shown us his character for decades and there are very few spots on it. For the most part, this looks like Brian dragging Will and his company into something based on what might be other people's behavior.
Will and his legal team aren't going to play around with this, and I hope the end result shows nothing shady on his part.
