A kind observation that exclusively calling this place "Mastodon" has a bit similar energy as saying "I just sent a GMail."
"Fediverse" (or "fedi") is a more inclusive, general term.
Mastodon is just one of many software projects that talk to each other to create this multi-instance social network:

(kudos to @axbom for this fantastic infographic!)
There are blogs, Reddit-like communities, video instances and many more, all part of fedi.
I edited this toot, as there were many people pointing out it sounded "annoyed" or "scolding." That was never the intention, and I am sorry it came off that way.
That said, I do believe language matters a great deal: "The limits of my language mean the limits of my world."
I am not trying to convince you to always use one term over the other (I too sometimes use "Mastodon" in that context). Okay, maybe a tiny bit.
But mainly, I am trying to give broader context.
I have also seen a lot of people saying "well the app is called Mastodon" — sure, but there are a lot of other apps you can use. Tusky, Metatext, Fedilab and literally dozens more:

If you happened to download "Fedilab" first, would you argue the whole network is called "Fedilab"?..
And being aware that there's a broad spectrum of options might help you find a mobile app that maybe even works better than the official one.
@rysiek if you happened to download "Fedilab" first, you'd be a very handsome person with impeccable taste.
