I guess that may count for you, but I mean lockdowns within the OS itself.

I don't care that I can't run Linux on my Mac. If I wanted to run Linux, I'd have different hardware.

You can change that on T2-based Intel Macs, at least, just like on Windows: https://support.apple.com/en-us/HT208330

Of course, Apple as an OEM does not support running non-Mac OSes, so virtualization should still be preferred for most use cases.

That's why I'm saying anymore. It was the case but it is no more possible with the new Apple Silicone laptop.

There’s no indication from Apple that they are intentionally not supporting this feature - just that it doesn’t exist right now. That said in practice I never use BootCamp because the driver support is always sub-par. It’s a much nicer experience to virtualize, especially now that most virtualization platforms offer native support for Apple’s virtualization libraries, such that installing third party kernel extensions are less necessary now than ever before. (I think the only ones I tend to install now are Tuxera NTFS support which tends to be really high quality. Apple should just buy Tuxera and ship them natively.)

I guess Microsoft will have to hurry up and build an ARM version of Windows so they can keep the rounding error number of BootCamp users satisfied.

An ARM version of Windows has existed for almost a decade. In fact it's running on quite a few laptops right now.

Since 1997 to be exact. WinCE ran on arm since time immemorial.

There is an ARM version of Windows 10 that runs on the Surface Pro X [1].

Not only that, the first released version of NT on ARM was in 2012.

They had crappy code signing policies (only store apps on Windows RT tablet) which guaranteed poor adoption but that was a policy decision, not a technical one.
