See I think the act of him apologizing is important.
Let's keep this in perspective: Kopech isn't losing his job, he's not losing his money, he's not being suspended. He's had to answer to stupid and immature public writings when he was younger, that he has since deleted and now apologized for. This twitter stuff is new territory, and (having been on this site since a teenager) I guarantee you could find a previous post of mine that would be incredibly disappointing or horrifying to me now.
This is a good thing and it's an opportunity for teenagers, who struggle with the ability to comprehend the public-nature of their communications now and the same toxic in-crowd behavior that makes us sick to our stomach when we our older, to see this play out and think about how the way they talk sounds when presented outside their friends group.
And the way this is being held over him by some probably teenagers should hopefully be a learning experience for them.
