I’m not clear what you mean by this part of your post.
I think there are activities you can engage in that are not criminal (so yes, not guilty) that might still be enough not to want to associate with a person, not want them in your league, on your team, in your company, etc.
The trial result didn’t say it didn’t happen, it said the woman was ok with it. Or more correctly that she did not prove that she wasn’t ok with it. So what happened was not a crime.
I’d think some of those boys have grown up and that’s not who they are and they regret it beyond being sorry it became known. I guess some of them could still think it was all perfectly fine.
