Your posts here are so incoherent, it’s not clear what you are complaining about. Is it the term "Eastern European"? That isn’t a “Cold War-era classification” at all. The use of “Eastern European” in the archaeology and linguistics of the region goes back to the term Osteuropa in the foundational 19th-century literature.

If you lack any familiarity with this field enough to know that, then it would be wise to refrain from making pronouncements on the worthiness of this research. Also, the HN submission is a pop-sci article created by that university’s PR, it is not the actual research. The actual research can be found in the mentioned journal.
