Easy and sensible why you might be against this. The simple reality is that BIOS did not prevent you to run anything you wanted on your machine. Recent developments are usually to restrict the user, so any change would very likely be bad. Extrapolated experience does not need to be true, but it very well can be. UEFI secure boot is an example. Yes, it can increase security (although I think the threat is specific or outdated), but it can well be used to limit the user practically. And if such a mechanism is established, there will be a class system of trusted and untrusted devices. This is not a development that is hard to predict. So UEFI already failed to a large degree, at least regarding the openness of systems. It is no accident that some companies push these developments enthusiastically. It is not for user security, it is simply for market dominance.
