Intel now deactivates AVX-512 capability on new Alder Lake CPUs
And that would be fused on a hardware level. Whilst AVX-512 was not officially supported on the chips, it was useable on Alder Lake on several motherboards.
According to an unnamed source, AVX-512 has been fully disabled in recent editions of Intel's Alder Lake non-K CPUs. This was later confirmed by Intel. "While AVX-512 was not fuse-disabled on select early Alder Lake desktop devices," a company official informed Tom's Hardware, "Intel expects to do so on Alder Lake products in the future."
Most 600-series motherboards later received an upgrade that eliminated official support for AVX512. Surprisingly, several firms attempted to provide partial support via secret BIOS settings. However, this is expected to change shortly, since the revised Alder Lake silicon will no longer have this area of the device physically activated. If you want AVX-512 capability with Intel's latest designs, you'll have to upgrade to its more costly Xeon CPUs. Meanwhile, AMD is said to be adding AVX-512 support to its Zen 4 processors, which is an unusual twist if Intel continues to refuse to support the instructions on consumer devices.

If that's the case, they have to talk with OEMs and motherboards manufacturers to have it disabled.
It's a assumption.
This has more weight and probability.
Either way, we as customers are screwed by greed.
What's next, next gen Intel GPUs will have the pay for features traits?
Desktop Gpu's already have "features" disabled vs the "PRO" workstation gpu's.

That's great
still,sue the crap out them if you have an adl-s,they can't do that.
i agree at heart.
but being local and knowing Intel the way i do i'm not being snarky or an ass when i say that's why they have the lawyers.
so they can do as they like and outlast anyone to getting to and through a court case.
this is better off as a complaint to a regulatory body as that's free.
the sad truth is they know this will affect only a tiny sliver of folks to mass market sales, but a noticeable increase in xeon sales at the exact same time Xeon is under siege.
and yes it is exactly market segregation.

Intel reportedly dreams of a CPU ecosystem where they can sell only a few models of CPUs to every customer, and the customer then pays separately to activate different technological options in the CPU they bought, above the very basic, default limit. Your stance is on that side. Traditionally people like to think that they own what they carry home from the shop. Even if Intel didn't advertise a feature, like AVX-512, the chip did have it and it was possible to use it, even if it required some conditions (disabling efficiency cores). So, it was what the customer bought. From this point of view (or stance), it's a dubious move to remove the option afterwards.
You are right that it's not really comparable to a car's turbo charger because the turbo would naturally be used during every drive. Maybe it would be more comparable to a collision alert system that wasn't turned on initially, nor mentioned anywhere in ads or brochures, but by digging through the touch screen menus, a driver could turn it on and it would work more or less as expected. Then, when the car got a software update, it would disappear entirely. I imagine people who did turn it on and kept it on happily would be less than pleased by the update.
exactly right on the first paragraph, analogies are always rough on the second
