I get that board directors have a responsibility to the organization. I've served on nonprofit boards. I know what that means.
It does not mean you need to publicly agree with all of a board's decisions.
Again, this is bonkers. It's 3:00am where I am and I'm just kind of sitting here gazing into the middle distance, wondering whether I need to start a new nonprofit just to allow big tent open source to have a voice that says: "You matter, your rights as an author of FOSS matter."
