Presumably, my understanding of Cloudflare is too simple, too rudimentary, or even entirely lacking in some aspects.

As far as I understand it, the main feature is just faster and more reliable access to sites, right?

If I host a website on a server in New York, and someone tries to look at it in Tokyo ... that's a long distance and a lot of potential hops to retrieve the file(s) directly from the NY machine. Cloudflare provides closer-location mirrors of websites so there is less lag time, plus having multiple copies makes my website more readily/reliably available.

That's good, I get that, especially for big, professional business-critical-type sites/services.

But it's not actually essential, is it? Anyone, anywhere on Earth could still visit my NY website w/o the existence of Cloudflare.

Is there more to Cloudflare than this? I realize they are getting into a variety of 2ndary "value-added"-type features, like their own "are you a robot" tests and probably a bunch of other stuff I don't know about ... but fundamentally, are they actually necessary for the Internet?

Why is Cloudflare such a big deal?

I am a big fan of Cloudflare Tunnels, it's let me muck about with quite a few low risk apps and it's been fun.

one thing that's always bothered me though is the SSL setup.

According to their website, only enterprise users are allowed to manage their own TLS private keys.

I can kinda understand the logic behind free accounts not having that perk.

But if you are someone who really doesn't like cloudflare reading your traffic or you are a business, it seems odd to me that it's not being demanded of cloudflare that they make it more available for paid users to not expose their TLS private keys to cloudflare.

Why are so many folks OK with cloudflare essentially being able to read all their traffic?

or am I overestimating how many people are using the Pro and Business account? is the majority of their users just Free or Enterprise?
