Its just the behavior of a monopolist where they are making their product line as efficient as possible by milking every last penny out of every single customer.
In a truly competitive ecosystem features that have additional cost would be the only ones that actually cost more, and artificial limits wouldn't work because the vendor with less market share would just throw them in for free.
So you would expect product segmentation along the lines of core counts, dram channels, etc but not really between for example high end desktop/low end server because there would be a gradual mixing of the two markets.
And it turns out the market is still competitive because Arm and AMD are driving a bus through some of those super high margin products that are only artificially differentiated from the lower end parts by the marketing department or some additional engineering time that actually breaks functionality in the product (ecc, locked multipliers, iommu's, 64-bit MMIO windows, etc).
