It's actually a social power attack, not a personal one. The "attack" (it's very hard to find any language in the post that could be considered an attack) is that patio11's advice is not great
for this specific case. It may look like a personal attack because why would someone post off-site just to comment on another person's comments?
The answer is, social power and the threat of in-group reprisals. If you challenge an extremely popular person's opinion, the in-group will attack you, because you basically just challenged their whole group mentality that this person is implicitly trustworthy and correct no matter what.
However, both of them have potentially bad advice, because they have a very small portion of a much longer story, and they both think they have the solution to something which may be much more complex. patio11's is more "nuclear", while the open mic author's is more "hiring is difficult and the incident may not be as horrible as it sounds so let's see if disciplinary action helps". Neither may apply, depending on all the left-out details.
