Why would learning how to fix a PC make you hate computing? If anything it makes you more confident in your ability to fix things if and when you break them. Likewise I don't get what's wrong with learning about Virtual Machines and emulators. PowerShell can't be that bad lol.
What it sounds like to me is you teaching your kids to think computing with Linux/FreeBSD is hard, and to hate using it. You're also teaching them to hate you for putting unnecessary barriers in front of them doing normal things like using a smartphone. Having a smartphone is necessary for modern life, as it does everything from communicating with family, finding out information, banking and booking appointments, ordering a taxi or takeout. Gatekeeping that behind arbitrary things like learning shell and setting up a web server is fucking dumb.
A taste of real things I'd want to give to help them connect their inner abstract idea of how the world works with actual material things. They will have that idea, I absolutely trust every person to develop that on their own without help. Without that they might not believe themselves when they should.
I don't even know what this is supposed to mean or how it's related to the things you are asking them to do.
I've said once that I want to give a taste of something. I was more general with things one can't avoid, as in "one can't avoid computers and the Internet". And this was pretty clear from the context, either you are playing dumb or you want to defeat someone in an argument, in the latter case I don't care because I see you are not doing that.
Not it wasn't clear at all, especially given the other nuts things you have said. You're also not winning this argument, look at who's getting downvotes here.
