I think my answer depends on whether the question of taking care to recognize is internal
e.g. "I'm using Mastodon, a popular interface using the ActivityPub protocol to connect with the social web area of the Fediverse, and Mastodon is not an endpoint/destination in itself."
which recognizes that other software and protocols exist without (explicitly) naming them
or
talking with different people, and for brevity doing a summary/tl;dr which will exclude things
