I only know the basics of networking, so I’ve been wondering why this “DNS-sinkhole” functionality can’t simply be implemented directly in private routers (as some kind of blocklist) instead of adding a new device to your network. Do routers not support this for technical or security reasons?

Routers are usually hardware level optimized for throughput, filtering is inherently computationally expensive compared to routing (not crazy expensive just more than usually fits an FPGA), especially if you have to keep up multi-gigabit throughput You could totally do it at the router, it would just become a more expensive piece of hardware and most people choose to cheap out
