Personal theory: Possibly the Great Attractor has something to do with a very large collection of dark matter - potentially dark matter galaxies. Hard to say though until we figure out how to see that section of space.
There no reason to believe dark matter had anything to do with the Great Attractor, it's just that we can't see it due to it being on the other side of the galaxy what makes it great
Read into it. Large amounts of dark matter fall into the one of several theories presented by the professionals as what could be causing the phenomenon.
I wonder if Zwicky had named it Gravimagic or Love (as later hypothesized by Captain and Tennille) if we would still be where we are in the understanding of the cosmos
Depends on what you mean by "we".
Scientists have a good understanding of what the data actually is. The name isn't important. It doesn't throw them off any more than the up and down quarks do.
Non scientists... yeah, maybe. There's a good chance we might never even have heard about it by a duller name. People fixate on charismatic ideas, disproportionately to their relevance or to their understanding.
It is possible that it helps indirectly. Students sometimes get bitten by the bug of charismatic science, and go into the field. And funders may well be influenced as well. That extra attention could put us ahead of where we would be otherwise.

I can't imagine how we'd ever find them. We'd have to get extremely lucky and find one that happened to lens another one behind it. That happens rarely enough with regular galaxies, and I imagine that those "dark galaxies" would be even rarer.
(And you'd still have to consider other explanations, like black holes.)
