Me personally? I might just let it happen (especially if it goes hand-in-glove with some other benefit, like lower cost). Or if it's too annoying I'll switch refrigerators.

That's the business model of the alternatives to Apple. Apple's business model is value delivered through vertical integration. For their end-users, they're building a better product because they own and control the hardware, OS, and software ecosystem.
It's Nintendo-Seal-of-Approval thinking, and it's not inherently wrong so long as there are alternatives (and there are many, just none that have a supported path to using Apple's hardware).
> You're arguing that Apple shouldn't do good things because... Apple doesn't care?
I don't think Apple sees opening the bootloader as a good thing. It increases the ways the machine can be in a broken state with the only benefit to people tech-savvy enough to just use other hardware. And, of course, from a pure-business standpoint, it might kick a leg out from under the money-made-through-vertical-integration stool, which is of concern to them.
