That's a comparison which serves nothing.
VtR and VtM are completely different games. They have shared elements, but Requiem was explicitly and obviously a different game. Exalted 3e, as is somewhat a clue from the name, a new edition of the same game rather a new property.
That's missing the practical, on the ground history they share, and the conceptual linkage between them. My point isn't to suggest they're right or wrong to call what they have in 3e Thaumaturgy. My point is that when people see the same word in these things which are conceptually similar but not the same, it can serve as a barrier to understanding, and trying to point that out to aid in understanding the thing on its own merits is a good thing. It isn't to deflect criticism, but to facilitate other kinds of criticism which might be more directly pertinent to the thing itself.
You can't dodge such comparisons - especially when Exalted 3e was so shit about how it handled thauamaturgy.
You absolutely cannot dodge comparisons, which is why it's all the more important to point it out, because you can get it out of the way that if you try to look at this thing as recapitulating the thing it shares a name with, you won't like it. If you look at it without that, you could, possibly, maybe, like it. It might serve to help alter the way you frame your understanding, so that if you're identifying problems, it's not merely that it isn't the same, but problems that are within the context of its presentation.
Anybody can say "I don't like the Nosferatu because they don't look at all like Count Orlok." But it might be helpful to those people to point out that they're not the same, because when they give it a chance and give it a read-through without that conceptual baggage, they might see that the new way their Curse works is intriguing for them, or they might even be able to identify problems with the premise of Requiem's Nosferatu that
aren't just the fact that they aren't the Nosferatu of Masquerade.
Again, it isn't about whether it's right or wrong to share the name, it's just about helping people to navigate the concept when they might get stuck on that association. For some of you, evidently, that's enough and you're good with that. It might also be valuable for people who don't categorically reject 3e Thaumaturgy to to identify problems within the context of the idea that aren't merely that it doesn't work like 2e Thaumaturgy and doesn't serve the same purpose.
Gotcha
@Omicron
Hmm. It's a legitimate criticism, but your main problems seem to be with how the fandom interprets the setting, versus the actual words dedicated to Thaumaturgy.
It sounds like it's both, because both the books and the fandom did that.
