I mean, some parts of the protocols we use for the Internet need to be in the clear to work, DNS comes to mind. If you want that kept private as well you need to use something like tor.
But regardless, what people generally actually care about keeping secret is the content, not the protocol.
Not really. We also have DNS over HTTPs, DNS over TLS, and DNSCrypt which are all becoming more popular. But that's still application level data that I'm not really talking about.
A lot of information can be gleaned from protocol metadata though. Source, destination, which applications are being used, maybe more depending on protocols. Not exactly information I want to be easily available to the public, but also not exactly critical either.
