Seems to miss the point when three of these are the largest cloud infrastructure providers out there. If you could detect the processor and blocked everything that pinged a server using Intel, you'd block 90% of the Internet. If you blocked anything routed through a router owned by Cisco, you'd shut down the entire Internet. Anything that loaded from a disk made by Seagate or Western Digital, memory made by Samsung, fiber backbone owned by AT&T. Every level of the hardware supply chain is dominated by a tiny number of huge companies. If that's really a concern, we're well past the point where we can do anything about it.

Personalized ad profiles and cross-site user tracking we can maybe still stop, but it's looking at the wrong thing to just flag any resource based on the IP block owner.
