A fight between awadhi and Bhojpuri

Why bhojpuri people are so dominant over Awadhi? They claim everything about East and Central UP as bhojpuri. Everything about folk culture language and songs of Awadh are owned by them are wikipedia. People just search things from wiki and post on internet. How is Thumari Bhojpuri? Kajri is from Mirzapur. 80% people from Mirzapur is Awadhi and kajri originated in Awadhi area. Why don't they give credits to Awadhi. Just because we don't care about our language.
