Actually you should read the article first before preaching it. This finding details only the Corona Borealis constellation. Not the entire sky. Maybe try reading beyond the first paragraph next time.

Hipparchus is thought to have charted the entire night sky and click baity articles like this create the impression that this discovery is it. They bank on the fact that people like you just read the headline or first paragraph and become experts on the subject.

I read it. Try again.

This catalog has been alluded to over the centuries by ancient texts but no one had any surviving proof. Ancient texts make vague allusions to Hipparchus' catalog but no one had ever actually dug up the catalog itself. While the deciphered piece is only partial, it's compelling proof that Hipparchus did produce a catalog of stars, and given testimony from other ancient astronomers who saw it in whole there's good reason to believe it was exhaustive.

Ancient peoples were citing this work for centuries. It was lost at some point and scholars have been trying to find a copy for centuries. It's pretty incredible to find pieces of it written over and hidden in documents we've been sitting on the whole time
