Macs ship with SIP enabled and it's easy to disable, I don't know what the (comparable) issue is there?
Again, not that I'm at all an Apple/Mac fanboy, I've had one personal Apple device (2013 Air) and a couple of work MBPs since. If anything macOS could be credited with moving me to Linux. Before it I only really knew Windows, but now I'd say 'Linux is what you make of it, macOS is just about manageable, and Windows is what it is'.
I generally use a Mac too, connected to Linux systems, but from the last time I disabled Secure Boot on a PC, the process was press F2 for Setup, go to the System tab in the BIOS, and uncheck Secure Boot, Save.
It's not particularly harder than a Mac: Restart in Recovery Mode, Launch a terminal, `csrutil disable`, Reboot.
> though for requiring it I suppose
Just like Mac "requires" it? I guess I just don't see how this is a "Windows sucks compared to Mac, let alone Linux" thing.
A non-technical user could disable SIP, though they'd never need to; good luck to them upgrading to Windows 11.
Newly requiring it on upgrade when it's hard to do and hardware may be incompatible anyway isn't great IMO. It's not really protecting anyone from anything, because it just leaves them unprotected in exactly the same way on the older OS. As long as they don't brick it trying.
