I get what you're saying, and on a philosophical level you're probably right. If a website owner misconfigures their CDN to the point of impeding legitimate traffic then they can fail like businesses do everyday. Survival of the fittest. But with the majority of web users apparently running stock Chrome, on a practical level the web still has to work. I went looking for car parts a number of months ago and was blocked/accosted by firewalls over 50% of the time. Not all Cloudflare-powered sites. There isn't enough time in the day to take every misconfigured site to task (unless you're Bowerick Wowbagger [1]), so I believe the solution will eventually have to be either an altruistic effort from Cloudflare or from government regulation.
