I found it cool also and ultimately I'm Filippo's boss. The fun part is that he found this by accident while debugging a customer problem and he worked quietly with F5 to disclose (so quietly I found out about this a couple of days ago).

Also Filippo does a good job of telling the story in his blog post. I don't get the "fallout for F5" part. A bug was found, a vendor informed, everyone worked together in a responsible manner. Happiness!

It's a story about competent people handling a bug responsibly. Nothing sensational, but deeply satisfying nonetheless.

It's straightforward, it's not trying to shill Cloudflare products too much, it's not self-congratulatory, and it's told from the chronological first-person perspective of an engineer trying to debug a protocol issue and accidentally uncovering a critical vuln.

Basically, it wasn't written by a marketing department like most of these other company-found vuln disclosures.
