I'll only say no to this question because I don't want to have kids. But I taught my mom how to pirate, and I'm proud of that. I believe that piracy is not a morally neutral act. It is morally good. Pro-piracy is an ethically good stance to take in this age.

I haven't taught my kids. . .yet.

However, they know that if they can't find something they want to watch, they just have to ask me and I'll get it from them. . .and that (sarcastically) "daddy is just borrowing it from the internet" so I think know what's going on.

i would teach my kids that piracy is the natural market force to push corpos and companies into ethically (or at least more ethically) distributing content.

I would also teach my kids that if one were to pirate media, they should also find a way to support whoever it came from directly, assuming it's a band or small artist, rather than something like a TV show, where it'll make no difference.

I’m a capitalist but even I think visual media needs a come to Jesus. If they had adopted the Spotify model everyone would be a lot happier. I would be paying for content still. Instead they broke up into a dozen different services with walled content. This is so stupid. I have no qualms keeping my own collection when this is the paid offering.

I'm not sure. I don't plan on having kids, so this is a purely theoretical question that I won't have to answer in practice, but I think I probably would, at least to some degree.

I had a pretty iconically millennial childhood when it comes to tech; I remember my mum being on the phone to the internet people and asked "he's offering me an unlimited packaged for [money] extra. Is that good, do we need that?", to which my brother and and I vigorously nodded. We were young enough we didn't know shit, but unlimited sounded good and we weren't paying the bills. My mum probably realised we didn't know what unlimited Vs metered internet meant in practice, and opted for unlimited as the safe option, because if she felt the need to ask her children for advice, she wouldn't be great at managing a metred connection. That's the context in which I grew up and is why I'm as techy as I am today.

I learned the hard way, and whilst I don't think that's necessarily the best way to learn, I don't know how one might teach people how to recognise which "download" button to press, and when a dodgy looking site is actually dodgy. It's like internet street smarts, but what that means has changed since I was a kid, and I don't necessarily know how I'd teach that beyond the basics, like installing adblockers and other common sense things.

I would if I had them.

It’s always advisable that you teach people how to use anything safely.

This really seems like a non-question. What is there to debate?

Sonarr/Radarr etc make it very easy and safe for media, but apps and games would be more of a serious sit down and talk kind of situation as more can go wrong there.

They'll learn on their own when asked to pay hundreds of dollars for a single textbook.

Speaking personally I don't know if its something I'd bring up to them, but if the topic comes up naturally I'd be honest about doing it and my moral reasoning for doing so. If the kid shows an interest or a curiosity about it then we can sit down and I'd teach them my ways. I took some stupid risks while I was still learning that I'd like to spare them from taking. Besides as you said it is technically illegal and if they are going to do it then it's best that they be doing it safe. Especially seeing as they would likely be doing it in your home.

It lead me to learn so much about servers and automation as well as everything I've learnt from material I've acquired

Children playing on a computer unsupervised has to have rules and boundaries (and physical backups). No, I'm not going to teach children, who are not even in their teens, to download or install anything, ever, unless I want them to learn about ransomware specifically.

If buying isn't owning, piracy isn't stealing.
