You’re thinking about this from the perspective of good faith. I think the people who are worried are looking at it from the perspective of no longer being comfortable saying something is too absurd to happen.
For example, say your company ends up on Matt’s legal radar and he trawls the logs looking for accesses from your IPs and says you violated CFAA – even if you’re totally comfortable that you’d prevail in court, that could be an expensive process and discovery might turn up things you’d prefer not to be public. In situations like that it’s easier simply not to risk dealing with him since people who are focused on vengeance will often waste resources on pointless activity just to prove a point.
