Having Google crawl everything on an Open Web is immensely preferable to the alternative of a closed web, or no web at all. Part of uploading things to the internet is reconciling that
everyone can see, copy and distribute the content you provide. It's part of authoring
anything digitally, and a poor boogeyman in a world where the Open Web has few demonstrable harms.
What should really scare people is the prospect of a common interface like the internet disappearing and being monetized by private interests. We take the Open Web today for granted, and while I partially feel like Doctorow is too fatalist, I also agree that interoperability is a core part of what makes the web function.
