Not so much according to that thread AMD already does it.
AMD has been selling their quad cores as triple cores at a lower price since forever. CPUs from batches that might have one defective core are rebranded and sold. 99% of the time you can unlock the deactivated core any you'll end up with a "more expensive" processor.
This is the exact same thing, only it's official, supported, fool and idiot proof but it costs money. You're not paying more for an inferior product: You're paying less for a product that could have been (but isn't) better.

Except those cores aren't stable. Run something like Prime 95 for several hours and you will hit issues. This has happened on every single unlocked Phenom II I've had a chance to dick with.
It's not noticeable in anything approaching common usage for most people, but real stress exposes the flaws in the core.

Yes! There's a difference between selling chips with a defective core as a 3 core and just locking one perfectly fine one off.

People look at me like im nuts telling them that i can make their dual core Phenom II a quad core.

Don't you have to have a motherboard that supports core unlocking though?

How would they unlock it? Special software? What's stopping people from just pirating it/unlocking it themselves?

Software, but I believe it requires a code that's unique to each processor; I think it will be non-trivial to pirate.

I bought an AMD Phenom II X3 that is now an X4. You have to buy a motherboard that supports core unlocking. It's very simple to do as long as your extra cores aren't defective. Upon booting the PC you just go into the BIOS and select something like 'enable core unlocking'.
