Piracy is a great example of a topic where legality and morality aren't the same.
Those kinds of topics are incredibly valuable teaching moments for children.
I would teach them when they are mature enough. Help them understand why some people think it is wrong, when/why you think it is acceptable, and how to do it safely.
You can teach them the difference between actual theft and copying. Explain how piracy has benefited humanity as a whole, explain why knowledge and cultural experiences shouldn't be gate kept by mega-corps from underprivileged people.
There are so many valuable lessons that you as parents could pass on to your kids through the topic of piracy.
And as every major platform enshitifies and information of all kinds gets locked behind more paywalls, piracy will become a more and more important skill to have.
As an IT sys-admin, you're largely correct. We are losing the essence more and more of proper sys-admin work.
IT staff are becoming more ecosystem maintainers than actual integrators and solutions experts. Instead of doing deep research on the problem and architecting actual solutions, many sys-admins just send off a quote request to a single external vendor and then call it good.
The research, quoting, planning, implementation, configuration, testing, monitoring, and maintenance are all outsourced. The sys-admins are just left with a simple web dashboard or desktop app that they often don't even understand well, and a support line for when things need to get fixed/upgraded.
It's a glorified help desk position in many cases. I've worked with several 10-15+ year admins that don't even know how to spec out a server, how to architect a basic network topology, how to optimize a SAN or NAS solution, etc.
They go with the default without a second thought. Email = O365 Office apps = MS Office suite Virtualization = VMware/Azure/HyperV Servers = HP/Dell
And because they are used to it, it propagates onward. If you want to break out of that, you have to be intentional every step of the way.
