Nandamuri Balakrishna's NO for any brands, reveal reason why?

Lately, during a media chat, South megastar Nandamuri Balakrishna stated that he never promoted any brands commercially, as it was unprincipled to use his fan following to endorse a brand.

He further went on to add that one of the reasons for not endorsing brands is his father Nandamuri Taraka Rama Rao. He apparently revealed that the fans and film viewers have loved him and his movies right from his first movie. Nandamuri Balakrishna feels that it would be wrong on his part to use his position as a star to endorse brands among his admirers and followers.
