I know the context, but that's irrelevant here. Whatever the cause, a root cause analysis pointing back to CF is nice for CF to help solve the situation, and is even nice to have for us tech enthusiasts here on HN (though it should still maintain professionalism). But for customers and decision makers at companies that might be looking at considering purchasing Cloudflare, you know what I
don't care about? Who's fault it was. There are multiple buckets of companies here:
1. Cloud providers that were effected enough to apparently devote not insignificant CEO and CTO time to it (Cloudflare)
2. Cloud providers that were affected but seemingly not enough for it to even register as anything more than a blip on their status tracker (Google, AWS, etc)
3. Cloud providers that weren't effected
As a potential customer thinking about buying services from one of these companies, which one do you think I am doing to do with? It certainly won't be CF. And if I am already engaged with CF, I want to know what CF is going to do to mitigate this situation in the future, and no, pointing fingers like a child and saying "it wasn't our fault!" doesn't count.
Cloudflare can't really control Verizon's actions that lead to this situation, but they can control how they respond to it and mitigate it. They had an opportunity to stand up as a leader and improve the internet (which is literally their company motto). As you pointed out, the internet working correctly is a matter of companies working together as good actors, and getting these companies to work together via good, strong relationships is a part of that.
Did Cloudflare do that? Nah. Instead, they made a petty blog post and their CEO is on Twitter telling Verizon they should be ashamed. I don't know exactly what his goal there was, but I assume it has something to do with hoping they'll be better in the future (if that's not his goal, then it really is just petty finger pointing). And if Cloudflare's CEO's method of getting people to improve their work is to publicly shame them, I really feel bad for anyone who works under him.
