Since when is peering not part of the Internet? Since when is even on-net caches not part of the Internet?

I always thought if I am on the Internet, anything I ping is "on the Internet". (I am intentionally ignoring things like split tunnel VPN nodes.)

Perhaps you think of the "Internet" as the "tier ones" or something?

I guess you assume smaller ISPs don't peer? Unfortunately, reality disagrees with you, 100s if not 1000s of times.

Still confused about this whole notion, though. Perhaps you can clarify?
