As others have said, this article is mostly nasty rhetoric with very little substance. I'm surprised that the CAPTCHA isn't accessible, but that's about it.

Websites opt-in to CloudFlare DDoS protection. If you want to be crawled, you don't have to use it. But it's very difficult to expose yourself to the open internet nowadays unless you're hosted in a cloud or have something like CloudFlare.

I have stuff I don't want crawled at all, I use CloudFlare, and it's an awesome (free!) service that helps me maintain HTTPS certs and keep Chinese and Russian IPs from hammering my server.
