By the only definition of the Internet that matters, the function "is on 
the Internet" is very much in the eye of the beholder.

Using this definition, v6-only services are most certainly "on the 
Internet" for people who have v6 connectivity. Similarly, various 
instances of the Pirate Bay that have v4 reachability are not "on the 
Internet" for end-users in draconian jurisdictions like the UK. Trying 
to make assertions about what "on the Internet" means in a general, 
global sense is an effort doomed to failure.

I realise you're talking in pragmatic terms about services that have a 
general, dispersed, global end-user population, but not all services are 
like that.
