Why do Telugu people seem to not know that that most of their surnames are toponymic?

Most Telugu surnames are toponymic. What this means is that most Telugu surnames are the names of their ancestral villages from many years ago. This is why Telugu surnames tend to end in village suffixes like uri, uru, palli, parthi, pudi, ganti, konda, kota, mili, etc. However, most Telugu people seem to not know this. Last year, there were Telugus on social media arguing about Usha Vance’s caste by stating that “Chilukuri” is used by one caste or another. The surname “Chilukuri” doesn’t have to do with any caste, it just means that her ancestors lived in Chilukuru at some point in time. For example: Ram Charan Konidela - Konidela, AP Balakrishna Nandamuri - Nandamuru, AP Venkatesh Daggubati - Daggubadu, AP Vijay Devarkonda - Devarakonda, TS Satya Nadella - Nadendla, AP Avantika Vandanapu - Vandanam, TS Aneesh Chaganty - Chagallu, AP
