> So that means that the only way that you can absolutely associate the project with Tony Iommi is the post in which the author says that it has nothing to do with Tony Iommi other than he's a guitarist like Django Reinhardt?

No, everything on https://iommi.rocks screams Tony Iommi, who was himself famously inspired by Django Reinhardt, because they both suffered severe finger injuries.

"Your first pick"... guitar pick.

"for a Django power chord"... Tony Iommi was famous for using power chords (in part due to his loss of fingers).

The sample code uses "Album" and "Artist".

Even the "rocks" in the domain name is suggestive.

> Seems like the opposite of a slam dunk.

> It's also 1) a very obvious and cute joke for people who are familiar with both guitarists

These consecutive sentences are strangely contradictory. Not a slam dunk, yet very obvious?

> you don't own your last name - although if you put "Iommi" on a guitar (or a studded leather jacket), you're going to have a problem.

As I said in another comment, this is not a trademark issue. It's good that you admit, though, that there are limits to using a person's name on a product. https://news.ycombinator.com/item?id=45758717

> But if you call your casserole recipe Iommi's Casserole, only a moron in a hurry is going to be confused. https://en.wikipedia.org/wiki/A_moron_in_a_hurry

Of course nobody is going to confuse a casserole or a Python package with a guitarist. But that's not the issue. Again, Tony Iommi is a person and not a product. If you market your casserole by giving the impression that Tony Iommi may have invented the recipe for the casserole, or at least knows of and endorses the casserole, that would be problematic.
