I'm not in a position where I'd have to make a decision like this, and I don't have all the information, but I like to think that if I had made a decision like this, I'd show some more respect in the aftermath.
Something more akin to: "That was really awful, I'm sorry. We were suddenly faced with the severity of our legal exposure and had to immediately lock everything down. It's not a reflection of trust or anything, it was legally what had to be done. Now that we've taken stock and are now squared away, we have to make a more explicit controls framework, and we hope we can make it up to you, make this right, and have you lead as a maintainer again."
...Then again, maybe this wasn't about legal exposure. Or maybe it was and former contributors/maintainers are getting apologetic emails right now...
