Eh. I’m really not a Linus fan but this doesn’t seem a big deal. They had a perfectly good interaction and they left on good terms. At no point was there any call or implication that the guy should get harassed. I also think that’s as gracious a response as you could ask. If the post is legit, I get why the Dad would be that way, but it doesn’t seem at all fair to blame Linus for anything there.
