I can see why one would be concerned about a heavily centralized DNS, but what I've experienced in the real world is that today's DNS gives me infinitely more options than I had back when I started on the Internet. Back in the day, you were often limited to one or two widely known public servers (MCI's for example) or your ISPs. Today I have tons of providers of public DNS, all with different advantages and tradeoffs, including paid features and support. This alone is radically better than the choices we had ~20 years ago. Add to that the fact that I can run my own caching resolver without reading a 642 page paper bound book (see pihole vs a dog-eared copy of DNS and BIND by Liu and and Albitz), and we're far from the dystopian nightmare you seem to be referring to.
