I’m sure most other applications are less Mac-optimized, though (software development, 3d/graphics editing, gaming, …).
As for piracy, it's just as easy on a Mac, and MacOS has more quality software than any other platform - unless you're talking about software used in factories and such.
But how many kids actually "save up" for a computer vs being given one by their parents or getting a hand-me-down from relatives? I would suspect that many parents would be more than happy to buy a Macbook for their kid if they showed that kind of interest.

This is simply untrue, and not something a tinkerer cares about on a general-purpose machine anyway (with my niece and son as n=2).
But for Linux, the creative software simply isn't there in many cases for a kid to start learning. Unless it's programming, which is not everybody's talent.
A kid tinkering with any kind of creative software learns and absorbs important skills which they can build on later if they want to. These things are much more valuable than system troubleshooting or becoming skilled in a game.
Are these not creative software? Perhaps not industry standard, but what is industry going to look like in a couple of decades anyway?
You can't really compare Audacity to Garage Band or GIMP to Affinity (which is now free).
I genuinely mean no offence, but you sound as an old serious man when talking about useful skills. Kids and teens are not doing this for their careers, they're doing this for fun.
Garage Band is free with a Mac...
And Logic Pro is a cheap subscription or very fair price when somebody like her is ready to take the next step. Maybe they even have a nice uncle who'd like to pay for it?
Yes, but depending on what you put in front of your kids, they're going to get different experiences when doing things for fun and curiosity. So why not help them a little on the way with the right tools and right toys? They'll find a way to get into the weeds and explore their curiosity one way or the other - isn't it much better that they learn about music or audio producing, or photo editing, digital art, or 3D modeling, instead of learning about how to fix the Windows registry or change a configuration file?
A kid will make a spreadsheet about dinosaurs if they only get to play with an office computer. Parents can help them by giving them something better to play with.
