Here's a thing to think about:
How many aftermarket boards are set up to allow or facilitate overclocking (usually with additonal options in the BIOS), and how many OEM boards are not?
And, how many of those overclocking options are used by the general public (answer, not very many).
So, here's the thing:
Most (if not all) of the same board manufacturers that currently support overclocking (and other user configurable options, like memory speed, etc.) aren't going to magically (and / or maliciously ) leave off an option that would be used by most of the same customers that use these other features.
My current MB is UEFI. It allows any OS to be installed and booted.
Yes, we should make ourselves heard, and let the board manufacturers know that we'll consider the option to disable secure boot a 'make or break' buying feature.
But, the betting odds are that (nearly) every aftermarket manufacturer will offer the option (why toss off a portion of your customer base by leaving out options?).
As far as the OEMs go, they're going to screw up their systems, just like they always do. The answer to that is pretty simple, 'DON'T BUY AN OEM SYSTEM' (at least if they remove your options).
See, this is the thing:
You WILL be able to acquire a UEFI motherboard that gives you the option to choose (or not choose) the secure boot option. There's a market for it, so there will be products to serve that market.
If you're that concerned about it, do your research, and either make sure that your OEM source isn't an idiot, or buy a standard aftermarket board that isn't crippled (and those *will* be out there).
There's enough to be worried about with the way MS does business, in many ways, but this is not as big of an issue as it's being made out to be.
Red Hat (and the others) aren't worried about UEFI systems that will exist and will allow the option to skip secure boot. They want the same ability to negotiate with the OEMs that Microsoft has, and while that may be an ideal and desirable position, it's not going to happen anytime soon.
But, to repeat (and repeat and repeat, ad nauseum): There *will* be UEFI motherboards and systems that are readily available and that either do not have secure boot, or that allow it to be controlled by the end user. Maybe some OEMs will buckle and screw their customers. Just avoid them. But you can bet (with a very high degree of certainty) that companies like ASUS, ASROCK, GIGABYTE, and so on, who make the biggest part of their business from hobbyist builders, will be more than happy to provide all of the options that their users want, including the ability to control the secure boot ability.
And to answer the (usually unstated or alluded to) point about the OEMs:
It seems as though a lot of this sturm and drang is focused on what the OEMs will do. Maybe they'll decide that it makes good business sense to stick with a single UEFI system that doesn't have the option to skip secure boot. And, you know what? They have that right. Maybe it makes sense for them to not have to code and test the option. And, you know what else? You have the equivalent right to not purchase their product.
As I mention above, the probability that every single aftermarket motherboard manufacturer will refuse to offer the option is so close to zero that it doesn't warrant serious consideration.
If you want one, there *WILL* be motherboards and systems easily available that give you the control you want.
Just buy one of those, and quit worrying about what Dell is going to give you.
