You’re absolutely right. The fact that people can work around the requirement for UEFI, TPM, and SecureBoot shows that it still runs fine on legacy BIOS. I’ve been saying this forever, it’s like a car radio company telling car dealerships to only allow them to be installed into cars with car alarms and then claiming that the radio is secure (when the security is a feature of the car, not the radio). It’s such bullshit…
I cannot install Windows 11 on my computer without using a hacky work around because Windows 11 “requires” SecureBoot and TPM, but my computer doesn’t even have UEFI.
