While it is good that you discovered leaked content is still out in the wild, your tone is somewhat condescending and rude. No need for it.
He discovered one of the worst private information leaks in the history of the internet, and for that, he won the highest reward in their bug bounty: a Cloudflare t-shirt.
They also tried to delay disclosure and wouldn't send him drafts of their disclosure blog post, which, when finally published, significantly downplayed the impact of the leak.
Now, here's the CEO of Cloudflare making it sound like Google was somehow being uncooperative, and also claiming that there's no more leaked private information in the Bing caches.
Wrong and wrong. I'd be annoyed, too.

I can see a whole team at Cloudflare panicking, trying to solve the issue, trying to communicate with big crawlers trying to evict all of the bad cache they have while trying to craft a blogpost that would save them from a PR catastrophe.
All the while Taviso is just becoming more and more aggressive to get the story out there. 6 freaking days.
short timeline for disclosures are not fun.
Two questions came to mind: "how do we clean up search engine caches?" (Tavis helped with Google), and "has anyone actively exploited this in the past?"
Internally, I prioritized clean up because we knew that this would become public at some point and I felt we had a duty of care to clean up the mess to protect people.
Has this question been answered yet?
Wouldn't your team now even have to decide how to deal with this even after some specific well known caches have been cleared? I mean there's no guarantee that someone may not have collected all this data and use it to target those cloudflare customer sites. Are you planning to ask all your customers to reset all their access credentials and other secrets?
There are very good reasons to enforce clear rules like this.
Cloudbleed obviously falls into the second category.
Legally, there's nothing stopping researchers from simply publishing a vulnerability as soon as they find it. The fact that they give the vendor a heads-up at all is a courtesy to the vendor and to their clients.
It is the norm, and it is called responsible disclosure. You're trying to do the less harm, and the less harm is a combination between giving some time to the developers to develop a fix and getting the news out there for customers and customers of customers to be aware of the issue.
I would also advise you notify your cloud-based services' customers how they might be affected (yes really), trust erosion tends to be contagious.
I think you have misunderstood the issue. Just because YOU did not use those services does not mean your data was not leaked. It means that other peoples data was not leaked on YOUR site, but YOUR data could be leaked on other sites that were using these services.
If this part is true, they're not vulnerable. Only data that was sent to CloudFlare's nginx proxy could have leaked, so if they only proxy their static content, then that's the only content that would leak.
The rest of their comment gives the wrong impression though, yeah.
The way it worked, the bug also leaked data sent by the visitors of the these "static sites": IP addresses, cookies, visited pages etc.
