The Steam Deck is software-freedom friendly

I might be missing the point of the author, but what's the difference between Steam Deck and a normal Windows gaming laptop in terms of software freedom?

Wouldn't you have more software freedom on Windows? Because you can run both Windows and Linux software (via WSL2).

I use macOS, Windows and Linux daily. They are all pretty open to installing and running your own software. And all of them have some sort of security measures that prevent you from running arbitrary apps unless you close some scary warnings or bypass it with some flags.

You can install Windows on the Steam Deck if you want.

But calling Windows more free than Linux because you can virtualize Linux is a noteworthy statement alright.

That's the exact argument people make on the Steam deck vs Nintendo. "but you can emulate switch games!"
