Very interesting, do you know where I can learn more truthful about the OG Greek yogurt. Does it have similar thick texture? I'm only finding vaguely trustworthy results and stories in google.

These were interesting:

It’s very thick, and the best of it is a mix of cow and sheep/goat milk. When I lived and worked in Cambridge, MA in the US I used to go to a local shop with the finest yogurt I’ve had outside of Greece (I miss it!). A shop called Sophia’s, run by you guessed it, Sophia, and they made their own yogurt. It’s thick, as in you can hardly shake it off a spoon thick, and very tangy. Compared to something like Fage, it’s less of a “gel” and more thick, and Fage tastes bland by comparison.

With honey, it’s the best thing in the world. Actually it’s still there according to the site, and according to the site it is strained.

... perhaps it should be called macedonian yogurt and this would appeal to greeks and bulgarians alike...

It'd be more safe to generalize it as Balkan.
