It's interesting to consider, and I don't know. I'm not a legal professional tho I imagine a legal professional would say "there's not enough information."
So on those points alone I feel it's far more likely what you suggest is incorrect. Also I'm inclined to believe that. One reason is it works to choose the benefit of the doubt (not only because it's a legal doctrine), one reason for that being the benefit of the doubt creates harmony amongst people. Search for the good, sometimes it takes effort, and it's worth it. You'll be happier, definitely, if you see the good. On that point, I'd say we're wired to imaginatively perceive the bad, because we're wired for "threat landscape analysis". Tho this disturbs the mind, and maybe isn't always a clarity that works for people. Seeing the good is more unnatural and yet I think also very valuable.
Finally, if a person is asking strangers for advice at a pivotal moment, I'd say they're valuing and respecting others. It also works to respect their vulnerability in reaching out and help. I mean, that's the putative spirit of "Ask HN", right?
Maybe I'm missing something here, and benefit of the doubt goes a long way it seems to me. I'm also finding the HN Guideline, "Don't say anything you wouldn't say to someone's face" really useful in guiding choice on what to say here! :)
I say don't do it if it is not your business, if what the person did did not intentionally physically, financially, emotionally destroy anyone.
If you do it, who would you be helping?
There is something I love about the law, a concept named balance of hardship. If the testimony will do damage to this person, while on the other hand only inflicting slight inconveniences for the business, than again don't do it.
EDIT: Now if the person knew the consequences and intentionally wanted to harm, then I guess they knew what they were getting into.
In general, however, I don't think that I would want to work for a company that would hold a bias against me due to my participating in presumably honest testimony when a previous employer was brought to court for whatever reason.
Looking for advice about what testifying could do to his career image in the long-term from a crowd that likely has relevant experience is about career impact. Explicitly.
Except it really isn't about the explicit literal question, it's about the unasked real question.
What happens when you don't know you don't know something, or when asking what would be unacceptable?
A proxy question is substituted, and you hope someone hears what you're really saying.
Also, from a literal sense, I'd say whether you feel the choice is authentic is actually all about career impact. You're choosing to make your career something which isn't you, or something which is. What is the impact on you, and subsequently on your career, for each choice?
Thanks for saying that you're right and that my answer isn't addressing the question. I invite you to create an answer that addresses the question you see, so we can learn from you! :)
There was a time when I didn't know how useful "being yourself" was. I don't believe I'm the only one. For instance, people substitute defining themselves by a contrarian viewpoint relative to others, until they work out who they really are. Case in point: the petulant teenager.
And when you don't know you don't know, the questions you ask and actions you take don't display an understanding of that -- so it works to address the non literal if you want to contribute to helping people with those requests.
I hope this helps ! :)
Just in case I'm misreading you, this post comes across as quite passive-aggressive and patronizing given your opening line.
Anyway I'm trying to say something like:
Not everyone may know that. Being yourself is important, all decisions flow from your values works. Sometimes it works to address the substantive content of a question which may differ from the literal.
If you have any ideas how I can say this in a way that works, thank you :)
