Intel seems to be going for market segmentation, with AVX-512 only available on their server CPUs. The option to enable AVX-512 has been removed from Alder Lake CPUs since 2022, and there is no AVX-512 on Raptor Lake.

AMD also keeps making and selling Zen 3 and Zen 2 chips as lower-cost products, and those do not have AVX-512.

With AVX10 intel will make the instructions available again on all segments. SIMD register width will vary between cores but the instructions will be there.

I don't think it was intentional market segmentation, just poor planning: the whole heterogenous cores strategy seems to have been thrown together in a hurry and they didn't have time to add AVX-512 to their Atom cores in an area-efficient way (so as not to negate the point of having E-cores).
