And when your Cloudflare site is down, most of the Internet is down too! There's no downside!

That's true. It will be down much less often than a single server in someone's basement.

Counterpoint: that would require using CloudFlare.

That is, in my opinion, far superior to using a single server ran by "someone".

I guess that is the beauty of opinions: they can be different from person to person. In my case, I would rather avoid CloudFlare if possible.
