I have to say from a browser user's point of view this is an extremely confusing take (to put it nicely). From the point of view of a browser user, the browser is working as intended. It is CloudFlare's responsibility to live up to their marketing hype and stop DOS-ing the very real, legitimate, human users of these browsers. It is not the user's nor browser dev's fault you oversold your technical capabilities.
You also have to realize what you're doing is effectively trying to negotiate with browser devs while actively waging a denial-of-service attack against their users. How about you stop the DOS attack first and then come back to the table with negotiations? Show a modicum of empathy?
Very well said.
