Through in practice they can't really do so. Or they already would have done it years ago. What is holding them back is regulatory oversight, and the fear of it. So if they ever do so, it's not a fault of "secure boot" and similar, but 100% the fault of politicians seriously messing up their job. EDIT: You can also blame Apple, for constantly pushing in a direction where such regulatory oversight is removed. (END EDIT) IMHO Secure Boot and TPM are features I want in my system if properly implemented. A laptop not supporting some form of secure boot and TPM would be for me a reason for not buying it. (Through being able to use custom platform keys is also a must have for me.)
